Title: The discerning audiophile's choice of proper speaker wire. ($35,000 for 2.5m)
Post by: Wan Huang Luo on November 14, 2018, 07:43:09 am
I'm pleased to present the highest quality cable available to discerning electronics aficionados like yourselves.

I present to you, Masterbuilt Audio.

Discerning audiophile journalists at The Absolute Sound wrote a gem of an article linked below. I submit an excerpt:
Quote
The roots of MasterBuilt Audio can be found in the U.S. aerospace program, where these contractors developed wiring systems with low-reactance cable for use in the Apollo lunar missions and other NASA projects, such as the International Space Station. When the founder of MBA first chose to study metallurgy and electrical engineering, it was never his intent to design products for the high-end audio industry.

MasterBuilt Ultra Line are the apex of audio cables.  Although extremely costly to produce, the performance is well worth the price to music lovers who own the world’s finest audio systems.  Your speaker cable is the final leg in the signal path of your system and can drastically affect the performance of components both in front and behind it,  regardless of quality.  Ultra Line Speaker Cables are the finishing touch in your quest to reproduce a simulation of live music in your home.

 

MasterBuilt utilizes a proprietary alloy made from precious metals developed by the U.S. aerospace industry to approach as close to a zero resistance state as possible.  The resistance of the Ultra Alloy is so low that a minute voltage pulse would travel through the cable without audible loss.  This trait is critical for use in speaker cables by providing purity of sound, image focus, and an incredible dynamic range.



If you own a world-class audio system and haven’t auditioned the Ultra Line of audio cables, you owe it to yourself to hear how these award winning cables will drastically improve your system.

IMPORTANT NOTE ABOUT POWER CORDS:  Audiophiles should realize that the first component in the system is the power cord.  This “first component” must be distortion-free and able to conduct a very large amount of current and voltage into the component.  It is known that the musical signal consists of voltage and current sourced from the a.c. wall outlet, and the component simply “modulates” that power into a musical waveform. Inexpensive power cords that come with most components will add distortion or remove quality of the signal.  For that reason, a high quality and non-reactive cable should be used; once the signal has been corrupted, it is impossible to reverse this damage regardless of the quality of components that follow.

While incorporating the highest levels of MasterBuilt insulation and winding geometric technology, the Ultra Line have one significant advancement over all other lines by utilizing conductors made with a proprietary alloy from precious metals.  This super-pure transmission path provides a distortion free signal to your electronics that is unmatched and results in enormous levels of dynamic range combined with high resolution of fine detail. By installing Ultra Line power cords to a system, listeners are able to hear details never before experienced from their reference recordings.  Ultra Line are by far the apex of power cords and as such, belong in only the world’s finest systems!

The article about this cable dives off the deep end.

Quote
I replaced every cable in my system with an equivalent length and type of MasterBuilt Audio Reference. The full loom included four single-ended interconnects, one USB cable, one pair of bi-wire speaker cables, and nine AC cables. The retail price of the loom in this configuration was $70,775.

All cables take time to season and settle, but the MasterBuilt Reference cables seemed to require a longer run-in time than I’ve come to expect, even when using my cable cooker. As a reviewer who must routinely substitute cables and other components, I’ve invested in a cable burn-in device. The unit I own, the AudioDharma Cable Cooker 2.5 EFS, runs a continuous square-wave frequency sweep of about 1 VAC for interconnects and 22 VAC for speaker and power cables, oscillating from 0Hz (DC) to ≈ 40kHz, and back. Several days on this device is more effective than many weeks or even months of routine play. And in my estimation, it affords more effectual, not just more expedient, results that are unattainable by simply dropping the cables in place and playing your favorite burn-in material.

Yet even after being cycled through my cooker for what I have found to be the optimum period for most cables, the MBA References still took weeks after installation to offer their best. To be fair, I could have tossed them back on the cooker for another 12–18 hours, but I really wanted to hear them, so into my system they went. (Because such a cook-in device may require an expenditure that you don’t feel compelled to make, be certain to speak with your dealer about auditioning fully run-in cables in your system, as it makes a significant difference, particularly with this loom.)
I had some concerns early on, as the MBAs’ longer than usual run-in period initially left me wanting, until their abilities in revealing inner detail, microdynamics, and overall bloom and body fully developed. But mature they did over the next month to five weeks. Once they’d developed, I was offered remarkably good bloom with copious musical body, a crucial attribute that I find shamefully absent from several other pricey entrants.

After that final maturation, one of the first attributes to capture my attention was the MBAs’ ability to reach deeply into the nether regions of the bass, extracting detail and nuance with exceptional pitch definition. They created a solid sense of both the impact and skin tone from the kickdrum in the opening of The Eagles’ “Hotel California,” from the live Hell Freezes Over album [Geffen].

Audiophoolery taken to the next dimension over THAT song?!!!  :scared:

For a while now I've felt unscrupulous people are trying to one-up each other and see how far they can push it before even the most fanatic audiophile gives up. That being said, you don't need to sell many of these cables to make the whole endeavour worthwhile. That probably explains why so many try to push these kinds of products.

The mains cable, is it even legal to sell?

Surely the earth conductor should be able to carry the full current from any short and as the live and neutral are 10AWG, it should therefore be at least that size too instead of 12AWG?

Oh, and if we are going to work out the most expensive wire, then may I present:

https://highend-electronics.com/products/audio-magic-ultimate-beeswax-shd-fuse?variant=2513608638493

$225 for 20mm of wire.

So, 2.5M of it would be a bargain at only $28,125 but that fails to account for bi-wiring which takes us to $56,250.

And then we need to think about multi-strand, so, let's assume a paltry 36 strands per cable:

36 x $28125 = $1,012,500

Oh, but there's two of them, a snip at $2,025,000.

Per speaker.

$4,050,000

by 2001 he noted that some of the most successful cable companies with extremely powerful marketing campaigns failed to employ even the most basic principles of signal transmission, with many making hyperbolic technological claims that to this day go unchallenged, much less substantiated. Because of his love of music and his growing dissatisfaction with a good number of cable companies he saw as being less than completely honest about their designs

I installed12 of the Audio Magic SHD fuses in our system, I spoke with Jerry at length before trying one. They are very labor intensive to make, he told me sometimes has to make 2-3 to get 1 right. I don't care for the price either, however they deliver the goods big time.

Are they really hand made?
I find that hard to believe.

Nano-Liquid Premium Fuses
We are known for having the quietest, best-sounding fuses on the market today. When it comes to stopping noise, our innovative designs use a variety of tricks no one else does. We stop the elements from vibrating at 50-60Hz because this causes a lot of noise. This is accomplished by injecting the fuse with a proprietary liquid anti-vibration material that stops vibration in its tracks. Our Black Out mixture is also injected and neutralizes both internal and external EMI and RF waves.

What Makes the Platinum Reference “More Than a Fuse" So Fine?
Without betraying proprietary information, let me note that the More Than a Fuse dramatically increases the impedance from 0.2 ohms to 10 ohms at 10 MHz, thus increasing high frequency noise-rejection fifty fold over that of a conventional fuse. As a result of this increased noise rejection, one can hear delicate extended high frequencies formerly swallowed up in noise.

And because the Platinum Reference “More Than a Fuse” also reduces ultra high frequency noise by up to 46 dB or more, a ratio 200 times that of a typical fuse, high frequency harmonic texture is heard against a dead quiet background with a level of detail and refinement so sweet, delicate, and with such presence and immediacy—well, it will make you smile.

We could tell you this fuse is the truest, the purest, the most refined, natural, detailed, extended, airy and transparent fuse you’ve ever heard, and we believe we would not exaggerate, but with fuses, as with cables, the proof is in the listening.

That depends entirely on how it was mastered. If it was one of those "compress the crap out of it, master it for CD & Radio and then tweak it to not destroy the master on the lathe", then nothing. If it was more like the Beatles vinyl re-issues, where when the mastering engineer was asked "would you buy the CD or Vinyl", he replied "the vinyl, as that is what it was mixed and mastered for (even the re-masters)".

If I want to listen to Jean Michel Jarre I'll take the DDD mastered CD. If I want to listen to anything mastered pre-1983, I'll take the Vinyl rather than the re-compressed, re-eq'd peaky mush pushed out to CD down the track.

Horses for courses.

Wait a mo though, I reckon the way you fasten the cables to the wall has a bearing on sound quality too. My latest line of enriched uranium clips with antimagnetic titanium nails will cost you only $100,000 a box of three. When fitting, be especially careful to read the instructions on how to identify the vibrational nodes of the cable, and only clip to  the wall at those points.

Nah, while I agree CDs are often completely different to the original vinyl reproduction that's nothing to do with the format, that's incompetent sound engineers dicking around with and ballsing up the mix to make it sound 'better' on CD when what they should be doing is leaving it the hell alone.

Braided loudspeaker cables were popular in the 1980's, I remember it killed many power amplifiers. I think the capacitance is too high, not that Sansui did well back then.

That is possible but if the output impedance of the amplifier is not properly controlled, just having the wrong length of speaker wire can cause the same problem.  Whether the cable is braided or not should not matter.

Typically an output network is required to decouple the low output impedance of the amplifier from the load at high frequencies to prevent destructive oscillation.

A Zobel network is more for handling the reactance of the loudspeaker itself so it is part of the frequency compensation.  High frequency decoupling is provided by a low-Q inductor after the Zobel network.

Indeed, without the decoupling inductance, high frequency oscillation in the output stage can destroy the Zobel network.

Owner of three of those fuses here.  Don't believe what other people say, the yellow stuff appears to be non-polar.  Each fuse gets re-sealed to ensure the volatiles don't get out (it stinks -- don't open them, it ruins them!).

They definitely work.  I spent a bit more money on replacement leads for my unit (tip: gold plating is worth it), but I was lucky enough to get these fuses on special.  Price often gets discounted shortly after March, that's the quiet time of the year for them.

Since installing them: overshoot has significantly reduced and performance at DC is markedly better than before.  Current readings show performance is now much more heavily affected by cable AWG, ie they are giving me notable drop in internal ESR.  Can't recommend these fuses enough.

I only wish Extech was smart enough to have installed these things in the factory.  Would have been happy to pay the premium  :-+

When CDs came out, I couldn't unload my vinyl fast enough.  From discussions with some other tech types on some of the audio forums, it seems that many of the early transfers were done without added compression and those CDs still are considered among the best representations of the original master tapes.  Only situations where they uncovered original multitracks or better copies of the masters have provided a better sounding source for distribution - assuming they resisted the temptation to squash or overdrive the signal during the process.

The problems vinyl has are legion: cutting distortion + tracing distortion often exceeding 3-5%; frequency response which steadily deteriorates as linear speed of the groove decreases toward the center; fragile medium with no error correction; linear dependence on absolute and relative accuracy of the disc's motion.  I frequently have people tell me that they prefer the sound of an LP to a (properly mastered) CD; my response is "I can't stop you from preferring the multiple defects in the media, but don't tell me it's more accurate."

That would sound dreadful, and would I think be noticed and corrected quickly. A more common problem was that early CD players often used poor analog filtering techniques on the D-to-A converter output. That is why sound quality sometimes was worse than from a good vinyl turntable. Of course in those days all recordings started life as analog tape, and another problem was that CDs of existing music had to be mastered from old magnetic tape that had been in storage for years, whereas the pressings mastered when the tape was new didn't deteriorate significantly in storage.

Wonder if there have ever been any invitational events where audiophools were invited to compare these products in a blinded situation where they could not visually identify which ones were (or were not) being used.

In other words, a test to see if they could tell the difference between different kinds of speaker wire. I really doubt if they could, once you got above the really thin stuff.

Granted, I think that all other things being equal, thicker wire is better. The minimum size wire I use on my "real" stereo system is slightly bigger than most zip cord. Its maybe 14 or 16 gauge super thick zip cord. (Its also what I use on my bench supplies). And I also have some "monster cable" which I got for free.

Its basically just thick flexible copper wire. Its likely around 12 or 14 gauge. (Its hidden behind furniture so its a PITA to fish out)

I use these thick cables because my receiver can deliver a solid 100 watts per channel into even as little as a 4 ohm load.

I would be willing to bet money that even the most "discerning"  "audiophiles" could not tell the difference between something like it and any more expensive cable, no matter how thick or expensive, in a double blind comparison.

We all know this. They likely know it too. In private.

Dave - you could actually make this into an event. It would promote your brand as well as common sense, substance and sanity in audio technology.

Different cables would be compared, they could even bring their own $35,000 cables.

the only condition would be inclusion of some generic thick copper wire.

We would see if any differences could be discerned by them, the self-styled experts.

Or anybody else.

In order to give them the maximum benefit of the doubt, the speakers could also be any speakers of their choice.

They could bring their own speakers.

But, the wires would be hidden. It could be proctored by an impartial jury of engineers.

And the event should be videotaped.  This event would likely become a huge viral video.

Mind you, I was just looking at a roll of 'speaker cable' on offer in a DIY store, and I reckon spider silk would have a greater cross section. This is the opposite end of the problem; people who buy this stuff and put maybe 20 or 50 ohms in series with each speaker, then try the the audiophool stuff at $100 a metre, and report that it's a fantastic product.  Because in their case it DOES improve the sound quality. A lot.

Of course they could have achieved the same quality improvement with any decent piece of mains flex, but they don't know that.  :palm:

Mind you, I was just looking at a roll of 'speaker cable' on offer in a DIY store, and I reckon spider silk would have a greater cross section.
Recently, I bough 100 m of two core 0,75 mm^2 cable.

A problem with it came to my attention after I cut off a decent chunk for a friend and a few days later he complained that the cable is crap and that he can't solder it. I took a piece, tried tinning it and it went well, no issues, so I talked to the guy and asked him what was the problem. After all, he's 72 and has been tinkering with electronics for a good part of his life, so apparently there was a problem. He said that the cable takes solder once, but never again. I asked him to repeat that.
So, I take the cable again, tin it (no problem) and try to solder two ends together, but nope, it doesn't work. The cable repels the solder and I was unable to make the joint. I've never seen such behavior before.
I tried the flame test, and sure enough, it's copper clad aluminium.

I bought it in an electronics store. I asked for 0,75 mm^2 speaker cable, so yeah, if somebody bought that crap expecting copper, I wouldn't be surprised if they didn't get the result one would expect. Or if they are used to that, a proper quality copper cable could make a difference.

I brought some ten way server cabinets sockets and they came with 400- 700v 49 amp Titanex H07RN-F 3G4 cables on 4 pin BS4343 plug. The adaptors are big and won't look good where it is going and in space wise so I ordered some smaller 1.5mm H07RN-F 13A cables to wire to a plug.

When they arrive I will test the conductors under a flame just in case.

Maybe I can re brand the Titanex cables and sell it to the audiphools as I believe that is what they're doing.

It is unusual to find very thick, high current cables that are also flexible in the hand and connector-friendly. I would imagine that especially for somebody who does a lot of speaker demoing and switching having the right kind of cable and also the right (quick attach/quick release) ends attached to them is also important. 

Very thick but flexible wire,

Banana plugs or gold plated pins suitable for insertion in amplifiers and speakers, with clear and unmistakable color coding, thats a big enough improvement over plain wire that its worth putting some effort into making up a pair of speaker cables that do it.

 I would say that a nice pair of top quality speaker cables wired with nice plugs might be worth $20 to me. Significantly more than the parts cost unmodified.

So there we have a logical price.

How did we go from $20 to $35,000? Thats not just ridiculous, its totally over the top.

That much money could do so many much better things.

Active speakers can sound really good. Because they can incorporate a feedback loop that corrects a lot of distortion.

Plus they are self contained.

Mackie makes nice freestanding active speakers. I think one plugs balanced XLR cables into them. They can run off a generator as well.

A Zobel network is more for handling the reactance of the loudspeaker itself so it is part of the frequency compensation.  High frequency decoupling is provided by a low-Q inductor after the Zobel network.

Indeed, without the decoupling inductance, high frequency oscillation in the output stage can destroy the Zobel network.
Ah OK. I've seen them described in various ways but they've not been on my radar enough to thoroughly understand.

I've a pile of old audio/linear MOSFETs here which are earmarked for an audio amp 'when I get time' so I'll need some more reading to do I suppose.

Also in an average transceiver, the zobel network can be used to absorb all the RF on the speaker wires to stop it getting back into the audio PA. Basically it presents a low impedance to RF. This can make some wild and unexpected noises, particularly with cheap crappy low stability LM386's etc.

They are likely to refuse and stick under their slithery proprietary bullshit excuse just like how the Master Built cable of the first poster of this thread slithers about in the picture.

4. Stick it on that Audigoon website and the likes.

Here's a joke: Managing to steal them for a teardown wouldn't be a bad idea as they are possibly not worth anything anyway especially when they have the China Export logos showing on them.

Also in an average transceiver, the zobel network can be used to absorb all the RF on the speaker wires to stop it getting back into the audio PA. Basically it presents a low impedance to RF. This can make some wild and unexpected noises, particularly with cheap crappy low stability LM386's etc.

I almost hate those chips, I fail to understand why they are still so popular when there are so  many better alternatives.

There's nothing wrong with cheap and simple amp chips. It's just they are only good for applications with a local/internal speaker. They aren't meant to run with long cables.

The Boucherot cell (https://en.wikipedia.org/wiki/Boucherot_cell) does work for differential-mode RF picked up by the xover inductors, within one channel.

But I find stereo loudspeaker wiring makes an excellent dipole antenna for common-mode RF, between the two (L and R) channels.
If you ever scope or RF spectrum analyzer on the loudspeaker outputs, you can see a lot of RF there, more so with MOSFET output stages.

This is the only science I have, as far as audible changes occurring with different audio cables and wiring.
I observe say AM radio station 680kHz with one set of cables, and another set of cables shifts tuning to between local AM stations and less RF interference is seen and heard as mostly "grit" or rectified/demodulated AM roaming around.  Not a lot of designers poke around for RF in audio designs.

The fix I use is clamp-on ferrite cores, instead of spending silly money on cables.

Absolutely, there are plenty of nice, cheap, simple amp chips, my gripe is with the LM386 and its variants, they are nasty, unstable and noisy, there are many more small, cheap and modern amp chips that  perform better, are easier to make stable and require fewer components to work well.

I've had them from RS Components, Farnell, Maplin, the local electronics shops (used to be blessed with three in my small home town) and I may even have bought them from the UK version of Radioshack, Tandy, at some point back in the mists of time.

To defend the chip a little, I've never managed to burn one up in anything I've 'designed' but I've seen loads in kits, homebrew and even commercial stuff that have had problems.

They serve a purpose and are cheap but there are plenty of more modern parts that perform better, are easier to use, less prone to oscillation, deliver more power (if it's needed) and have nice features like DC volume control...

I’ve let the smoke out of a few. They still work while it’s coming out which is impressive.  :-DD

Main problems for me are the hiss (unless you apply one of the little tricks people worked out)  and the distortion. It sounds horrible. Fine for things like radios where the sound fidelity is crap anyway but not audio applications of a any kind.

They make reasonable “power opamps” though for low frequency stuff. I’ve used two of them to drive a motor for example.

Not convinced about  LM386 being OK for radio, I don't see why you'd want to add more noise or make it sound worse when it sounds pretty bad anyway?

As for power op-amps, which ones are you using?

I've casually looked around for a replacement for the L165V, I miss that chip, it was a really good all rounder and sounded pretty good as a simple audio PA.

LM386 is only "ok" on HF where the noise floor is pretty high anyway. Adding more noise and distortion to the audio chain doesn't really make it much worse than it already is. When the JRC clones appeared, the cost benefit of the noise reduction of a better part wasn't really worth the trade off.

Some of the cheap TDA series amps work reasonably well as power opamp, particularly TDA2040. That has decent open loop gain of around 20 up to 10MHz (not bad for an audio amp!), are virtually impossible to blow up and don't have any phase inversion problems. I tend to use an MJE3055 / MJE2955 pair and a TS922 driving the pair as a follower however because they are useful independently as well.

For people who want worse connections?

One of the nice things about UK sockets is, unlike US sockets, plugs don't tend to fall out and connections are generally much more solid. Australian plugs are mostly decent, as are some of the europlug variants.

At least for US folk (and others that use that plug, Japan, Canada etc.) the low voltage and often bad connectors does (sadly) justify some level of upgraded power connections, although of course that stops *WAY* below many of these things.

I totally agree. The AC power plug we have here in the US is not the best. It would make sense just as a short term fix, to invert it at least so that if a plug was not in all the way some conductive item falling from above would hit the ground first, and perhaps not bridge the contacts. At the very least the outlets should recess the plugs into the wall a bit more. That would be a backwards-compatible change.

So, since audio modules were brought up, what are people's opinions of audio amplifier modules that can be used to make a quick, basic audio amp for a work area?

 I may build it into a panel with some other stuff like a quick and handy power supply.

I like them, cheap and easy to use, the ones I use on the bench are TDA7297 modules, I've got a few TDA2030 modules too, I use those to replace fried audio amps when the original chips are obsolete.

They need a bigger heatsink but work well enough as supplied if you don't turn up the volume too much.

Does longer conditioning time mean better performance? Can I over-Cook my cables? Will they be damaged in any way?   
Over-Cooking can reduce the performance, at least temporarily. The characteristics of this are a reduced or diminished soundstage and a dull, lifeless quality to the music. If this situation occurs, merely letting the cables physically rest, and settle, then putting them back in the music system to play for a few hours brings them back to their optimal performance level. Over-Cooking does NOT do any damage to the cabling whatsoever.

You will never hear how good your cables can sound if they're not cooked and demos will seem pointless without a cable cooker.

I've made many bad cable purchases and the cycle was broken a few years ago when a local audiophile friend cooked at least 4 pairs of IC/2 pairs SC and I couldn't believe my ears. Differences between cables are easily revealed...

Every quarter I recharge all of my cables to keep them at their optimum level. This is a piece of equipment that all serious music lovers need...

Honestly in this day and age we should have the amplifiers in the speakers (active speakers) and differential (at least) or digital signalling. Then you can run it over wet string.

I've owned a pair of Genelec 1031A active studio monitors for 22 years now. They're biamped with an active crossover. XLR analog in. Attached to the TV is a pair of the KRK RokIt 5 guys, also biamped with balanced input. And I got a pair of the $99 Mackie biamped powered monitors, because I designed a couple of audio things and when testing I didn't want to blow up the Genelecs. (I haven't blown up the Mackies, though.)

One swab to wax them all,
And in the darkness bind them

Waxative free swabs and cotton buds with nanotechnology biotech solvents, Proprietary formula.
All cryogenically frozen.
Comes in special casings made of special precious laboratory metals.
See our demo featuring relaxed Susan.
Trial offer for Audiogoon members, only $125 for the first fifteen orders.


Any ideas for a cooker to go with it?
The swab shafts are carefully arranged and precisely spaced on either side of a hollow inner core in order to provide a perfect mechanical interface along the length of the swab. The meticulous layout of the gold-pressed cotton buds minimizes skin effect and reduces damping, while the meticulously formulated solvents reduce internal microphony.

I've been listening to supposedly some of the finest speakers that currently exist. These include b&w 800 Series, revel high end, vivid audio, Psi audio and kef blades.
They must have excellent hearing and I wonder if they would submit themselves to hearing tests to confirm how good their hearing is to notice the difference.

I think one because they are probably a centimetre from your ear drum and two they are blasting may100 db as well and maybe they have damaged your eardrums so much that you now can't differentiate good from bad. Them earbuds'll do it every time.


Somewhere up the thread and their hearing is going to or on Dire Straits:

Elizabeth,  I totally agree. I have noticed many recordings are crap. So I set up playlist of music that sounds the best to me. Dire straits,  Diana krall and quite a few others.

So it is the recordings that are crap and not your ears?

I see them going on Ebay and Amazon and want to know if anyone here has brought one and tried it.

I am looking to make my sound sound better with my MP3 players and car audio.

So please let me know your thoughts.

It was to do with the EEVblog #719 - Sony Low Noise Audiophile SDXC Memory Card.

Surprised not to see them talking about it and I'd though they would go crazy over mentioning it but it was a disappointment.

True, but the effect can be offset by implantation of de-nuetralized silver and then coated with phosphoric-implanted and clean-room prepared platinum. This procedure should be performed in a Zero-gravity area for best results, although it may yield an increase in performance without this step.

"extremely difficult to build considering Audio Magic is drilling into both sides of the fuse"

This sounds like they buy standard hollow 19 cent glass fuses (https://www.digikey.de/short/j1f7hq), then drill holes and fill it with something, really bees wax? And then print a label on it. I don't care if audiophools buy a $1 million speaker cable, but manipulation a fuse in such a way might be a fire hazard and even illegal to sell. Someone should buy it, test it professionally, and then sue the company who sells it.

Searching for more images just makes me think they probably buy a box of "whatever" from a wholesaler. Before modification they're almost certainly decent fuses that meet their specs.

And the MasterBuild website lists many distributors, the Nordost website even more: Just for Germany they list one distributor, and 59 dealers. Looks like there are really some fools out there who buys this stuff.

Looking at the feedback it seems he buys from China and sells things as well as those cables.

It is a cable and it is going to be plugged in most to all of the time so why bother putting a lock on it and why would anybody want to steal that peace of crap anyway and if they did they'd just smash the box open.

Or is it so precious it is intended not to be used at all but to be kept in there like a piece of jewellery for sentimentalists except this one does not have got any gold in it.

Everybody knows that wooden ferrite cores on power cables give you much more airy and natural timbre midtones with crisp and warm lows, but without the obvious sibilant and harsh highs you get with actual ferrite.
Furthermore, it strikes a positive balance with the natural wood the speaker enclosures are made from, resulting in lush and harmonious listening experience. They actively help in reducing noise in the mains, caused by outside factors, by adding positive mass to the cables themselves and enhancing the overall audio system.
Wooden ferrite cores likely have the highest cost/benefit ratio you could possibly invest in, and are a must for every serious and discerning audiophool.

I have a few in my shop, if you're interested. They're on Christmas season discount and usually sell for only $750, but with a 20% off coupon you can get them for $600.


How many do you think I would sell if I posted this on an audiophool forum?

Let's not forget the Maple and Mahogany wooden ferrite core plug-ons when listening to guitar based AOR tunes  8)

Besides the obvious timbre/timber benefits, the wooden ferrite acts as an electrical isolation barrier

especially in harsh hi-fi placement situations like on a polished wood floor with steel frame underneath of unknown grade,
added with the conflicts of deploying dissimilar weld joint and fastener metals used by clueless builder/tradies who can't appreciate a proper listening environment for hip hop and Bach mashups

 I only buy audio components which are perfectly impedance matched over the entire range from 5 Hz to 100 KHz.

Thus I require that any commercial audio cables I purchase  include a test report using a Keysight E5061B-3L3 with the 1E5 High Stability Timebase option from 5 Hz to 100 KHz for the serial number of the cable as well as the NIST calibration certificate with data and uncertainties for the most recent calibration of the E5061B.

After all, a person cannot be too careful.  Your ears are irreplaceable.  Just think of the damage that poor quality audio components can cause.  I am shocked at the utter disregard of certain forum members to this vitally important issue.

Audiofools hate double-blind tests because it exposes their nonsense beliefs to scientific scrutiny.  I participate on a forum where DBT has been used quite a lot to compare lossy audio to lossless - another embarrassment to the so-called "golden ears".

A computer magazine did such a test 18 years ago (https://www.heise.de/ct/artikel/Kreuzverhoertest-287592.html). The test setup: they used 17 different music pieces, and people had to listen to 1 minute CD quality first, then either 128 kbit/s MP3, 256 kbit/s or the same CD quality again, for 1 minute. So it was a A/B test. Unfortunately the article doesn't go into the details if it was a double-blind test, but I guess they knew what they were doing. The conclusion: nobody could hear a difference between CD quality and 256 kbit/s MP3, the 256 kbit/s MP3 was classified as CD quality as often as the CD quality test. But some people could hear a difference between 128 kbit/s MP3 and CD quality. But again, for some music, people thought the 128 kbit/s MP3 was better than the CD quality.

I think maybe an even better test setup than A/B is the ABX test (https://en.wikipedia.org/wiki/ABX_test), executed as double blind trials as well: "A subject is presented with two known samples (sample A, the first reference, and sample B, the second reference) followed by one unknown sample X that is randomly selected from either A or B. The subject is then required to identify X as either A or B.". The statistical results are less ambiguous than the concept with the arbitrary point system used by the computer magazine test. But I guess audiophools would argue that the relays used to switch the speaker cables influenced the sound, or other silly arguments. BTW, I think using mechanical relays could be a problem, because you could potentially hear different click sounds for different audio paths. Should be well shielded or very quiet relays.

Audiofools hate double-blind tests because it exposes their nonsense beliefs to scientific scrutiny.  I participate on a forum where DBT has been used quite a lot to compare lossy audio to lossless - another embarrassment to the so-called "golden ears".

A computer magazine did such a test 18 years ago (https://www.heise.de/ct/artikel/Kreuzverhoertest-287592.html). The test setup: they used 17 different music pieces, and people had to listen to 1 minute CD quality first, then either 128 kbit/s MP3, 256 kbit/s or the same CD quality again, for 1 minute. So it was a A/B test. Unfortunately the article doesn't go into the details if it was a double-blind test, but I guess they knew what they were doing. The conclusion: nobody could hear a difference between CD quality and 256 kbit/s MP3, the 256 kbit/s MP3 was classified as CD quality as often as the CD quality test. But some people could hear a difference between 128 kbit/s MP3 and CD quality. But again, for some music, people thought the 128 kbit/s MP3 was better than the CD quality.

I think maybe an even better test setup than A/B is the ABX test (https://en.wikipedia.org/wiki/ABX_test), executed as double blind trials as well: "A subject is presented with two known samples (sample A, the first reference, and sample B, the second reference) followed by one unknown sample X that is randomly selected from either A or B. The subject is then required to identify X as either A or B.". The statistical results are less ambiguous than the concept with the arbitrary point system used by the computer magazine test. But I guess audiophools would argue that the relays used to switch the speaker cables influenced the sound, or other silly arguments. BTW, I think using mechanical relays could be a problem, because you could potentially hear different click sounds for different audio paths. Should be well shielded or very quiet relays.

Yes, the ABX test is a superior scientific tool to perform DBT and that's what I use for audio codec evaluations.  In fact, a proper ABX test allows the user to select the material, the actual sample length and location, and run an unlimited number of selections before choosing each instance.  At least (I think) 16 instances per test should be conducted in order to exclude random choice to a <5% level.  Properly designed, it eliminates nearly all possible objections to the accuracy of the test.  Just FYI, I can barely tell 128K lossy from a lossless source on high quality material; the total test (I only managed 10 instances) lasted half an hour and was quite tiring because I had to strain to hear any difference at all.  It would have been entirely adequate for casual listening.  I'm pretty sure 192K or higher would be completely transparent for me, even with critical listening. 

There existed (and may still exist) an electromechanical test box for comparing amplifiers, cables, etc. which ensured that any audible/visual clues were obscured to the point that specific settings could not be determined independently.  I think it actually switched relays whether A, B, or X was selected, and ensured that the path was a constant length + same number of relay contacts just to eliminate another set of objections.  It was used by a group called the SMWTMS for numerous tests in which the fallacy of audible differences between cables, interconnects, and quality amplifiers was repeatedly challenged and defeated.

Oh good LORD ALMIGHTY but my head hurts after reading the ad copy (and ESPECIALLY after reading the TAS excerpt) at the head of this thread!  |O |O |O  I've been sitting on the edge of the audio world since I was a little kid, watching it all go down, and the capacity of the human animal to lie to himself and believe it just goes beyond all bounds in this environment.

(http://www.afn.org/~scotsman/graphics/baltar.six.self-deception.png)

I used to go round-and-round with a coworker who's a degreed electrical engineer and REALLY ought to KNOW better about the whole cables thing. Ah well, he doesn't have kids so it's not like he's squandering anyone's inheritance...  ::)

I am **SO** glad my granddad (one of the pioneers of this once respectable, now misbegotten environment) did not live to see the reasoned, conservative, well-engineered approach to high fidelity audio reproduction so marginalized by a group of people, companies, and magazines that make Amar Bose look like a pillar of moral rectitude and truth in advertising!  :palm:

Do it! Hopefully, they'll all stab their eardrums out with them and we won't have to worry about them anymore. >:D

I think one already went deaf.

I've been listening to supposedly some of the finest speakers that currently exist. These include b&w 800 Series, revel high end, vivid audio, Psi audio and kef blades.
They must have excellent hearing and I wonder if they would submit themselves to hearing tests to confirm how good their hearing is to notice the difference.

I think one because they are probably a centimetre from your ear drum and two they are blasting may100 db as well and maybe they have damaged your eardrums so much that you now can't differentiate good from bad. Them earbuds'll do it every time.


Somewhere up the thread and their hearing is going to or on Dire Straits:

Elizabeth,  I totally agree. I have noticed many recordings are crap. So I set up playlist of music that sounds the best to me. Dire straits,  Diana krall and quite a few others.

So it is the recordings that are crap and not your ears?

No idea, I recently picked up a pair of second hand LG LHS-W75TAF (6ohm, 200watt) speakers to pair with my audio unit (4-16ohm, 65watt), both seem to sound fine, though even my non-expert hearing makes me want to find out just what is inside the speakers, as I'm not sure if they are working correctly (When I pass below the mid plane of the speaker towers the sound is 'above' me.) I seriously doubt any audiophile would be able to tell much more than that.

That has been my experience as well. In a pristine audio environment maybe I *might* discern audible degradation in a 128k MP3 vs the source, but in the real world, noisy kitchen/living room at home, the zoo-like cubefarm at work, or God help us all the car, it's a non-issue. Compression artifacts are totally swamped by lousy car speakers and environmental noise.  ::)

I expect better screen printing for $35,000. It's not even embossed.

It's tempting to call you a Philistine, but anyway, it's clear you just don't understand. I shall attempt to educate you, although I feel it's a lost cause.

When assembling a top end speaker cable system like this, each part has to be carefully auditioned, not just for it's own merits, but for its ability to work cooperatively and complement other parts of the system. The lettering is not just an identification, it was chosen for its acoustic competence as well as its nominal role, and is workmanlike but is not merely functional.There is something of the artist about it, taking pride in its work and willingly going the extra mile, but it resists being a prima donna, a trap gold embossed lettering can easily fall into. It forms part of an exquisitely balanced team which can not merely cope, but excel with any programme material, Heavy Metal, Chamber Music, Gregorian Chant, Blues, and can make the best of any source, even making up for the glaring deficiencies of being matched with budget (sub $10,000) components. It plays its part in a whole which is definite without being overly insistent, and precise, but avoids straying into being boringly pedantic. It greatly adds to the presence. It plays a full and positive part in a very musical but restrained component system which many would describe as frighteningly revealing - especially about the sanity of anyone tempted to buy it.

Sorry about that. This thing is nonsense on stilts. Still maybe it's only jousting for silliness with audiophile mains leads of any sort - shouldn't purchasers also have their house wiring redone in at least solid silver cable?

I suppose on balance, this audiophoolery is a good thing. There's a demand and a market created and I doubt many kids are going to school barefoot because of it.

“Conductor Material:  U.S. laboratory grade precious metal alloys, proprietary formulation”

Meaning; 1% Copper, 99% Bullshit

I agree with you on this.
I admit I was stumped by his claim, after all since when is copper coated aluminium proprietary ?
For this price a gold plated platin wire would be appropirate.

Yes, in the car or just as background music, or with a lower quality recording, there's no way I could hear a difference.  The ABX test really requires each pair of samples to be compared, randomized, and compared again at least 10 times to be statistically significant.  It took me minutes of listening and repeated comparisons for each excerpt in order to hear anything at 128k - and to be completely honest, I have no idea what it was that I used to ID the differences.  It was a nearly subconscious perception of clarity or something, but whatever it was, I was able to pick 10/10 for each of the samples so it wasn't imagination.  After the 10 tests for each sample, I was very fatigued and had to take a break.  IMHO, anyone who says the differences are "obvious" has never actually done a scientific test.

There existed (and may still exist) an electromechanical test box for comparing amplifiers, cables, etc. which ensured that any audible/visual clues were obscured to the point that specific settings could not be determined independently.  I think it actually switched relays whether A, B, or X was selected, and ensured that the path was a constant length + same number of relay contacts just to eliminate another set of objections.  It was used by a group called the SMWTMS for numerous tests in which the fallacy of audible differences between cables, interconnects, and quality amplifiers was repeatedly challenged and defeated.

I love those guys.  They approach high fidelity in a rational, positive way and share their findings willingly.  No one stands to profit from deception in that group.  I just wish they were better known in the industry; the only way it seems you can get in touch with them is via email or snail mail, and their monthly meetings are livecast but not advertised anywhere except on their site.  At one time they sold the ABX box, but it seems hard to find info on it today.
