If you thought "audio-grade" power cables and plugs were silly enough...

There is one element of such a move that I can accept as valid - and that is the isolation from power pollution from other people's appliances, especially motors and SMPS... at least through conduction along shared power lines.

Otherwise .....

I'd be very upset if interference on incoming AC power made it through the power supplies of my excessively expensive audio equipment and affected the sound to the extent that I needed to pay $40,000 to have my own utility pole.

But, if the interference really does make a difference, why not just invest in an isolation transformer in a box and feed the room from that?

It's just another example of audiophool fashion from the golden ears who have more money than sense.

Off all the quack ideas put forth by 'audiophiles' the idea of reducing the noise that comes in on the power lines is the least offensive of them.  Of course a good power supply should eliminate almost 100% of such noise, but there is at least the chance that some would get through.  But, if that was the idea he'd have been better off making his own power and keeping it isolated from all other users/uses particularly motors and arc welders but even compact florescent lamps are kind of noisy.  Have a Stirling engine drive a generator with a HUGE flywheel...

So, although the idea of spending thousands to install your own power pole is pretty stupid it is less stupid than 99% of the ideas promoted by audiophiles...

It's good that he doesn't know how bad are devices connected to HV grid (for example water pumps running from 6 kV and so on, not sure what are the exact grid voltages in Japan) and how much "electromagnetic interference" (however he defines this term) he'll get from it;)

The separate power pole idea does something far more concrete than a simple isolation transformer.

It, more precisely the utility step-down transformer mounted on it, takes its power from a much lower impedance source.  One would expect this source will contain less "hash" from consumer appliances from neighbours, since those neighbours' conducted EMI will first have to get through their power pole transformer (with its effectively 'choke' action).  Once on the distribution supply side, this EMI will then be trying to to drive the lower impedance circuit.  I can see the attenuation being rather significant.

This attenuated conducted EMI then goes through our Japanese lawyer's pole transformer and is going to be many dB down as compared to pre pole conditions.

It's good that he doesn't know how bad are devices connected to HV grid (for example water pumps running from 6 kV and so on, not sure what are the exact grid voltages in Japan) and how much "electromagnetic interference" (however he defines this term) he'll get from it;)

Damn.... there goes a perfectly good theory.


On the matter of EMI in the lawyer's home, I suspect all SMPS supplies will be physically unpowered during a listening session - and I would bet his room lighting would be old-fashioned incandescent.

I would bet the rest of the household keeps the fridge door closed too, in case a loss of cold air causes the motor to kick in....

These motors are real beauties. This one works for powering the fan in coal mine, but a bit smaller ones are used for water pumps;)

I should have thought a little harder....

This also reminds me of the very first full-time job I had.  I worked in the EDP department (is that showing my age?) of a company that had several divisions - one of which had a computer program that was used in the design of conveyor belts ... ones 7 miles long carrying coal.

Even back then I was in awe of the mechanical and electrical considerations in starting one of those up from stationary.

Still, these spikes might be more tolerable than a constant SMPS buzz.

The only way to *really* achieve what he's aiming for would be battery supplies for all the audio gear, eliminating all the transformers and DC-DC converters, ideally using nothing that requires a clock source either.

In a Faraday cage designed to exclude all external magnetic/electromagnetic influences.

That's not audiophool enough. The most outrageous one is a piece of plain cotton cover that claimed to alter audio performance of the equipment covered by it.
Another one insane AP gadget is "magic rubber standing feet" that "alternates resonance frequency of amplifiers".

Well, it could, they never said what kind of resonance it is ;) When I put a food plate on one of my speakers it tends to resonate badly and make ugly noise, after I use a rubber mat it works just fine. I've got active speaker set so it does exactly as advertised when used on one with amplifier inside.

Yet another corollary to Beranek's law. It is the ONE reason to never ever mix loudspeaker engineering (filter theory, power response, optimization, TS parameter control, etc) with loudspeaker marketing (sounding, tuned by ear, cryogenically dipped earwax). It is as if they are not the same product.

The same law can be expanded to power supplies, capacitor upgrades, etc. The professor said it best. It is the power of imagination - and he called it sacred.

Beranek's Law

It has been remarked that if one selects his own components, builds his own enclosure, and is convinced he has made a wise choice of design, then his own loudspeaker sounds better to him than does anyone else's loudspeaker. In this case, the frequency response of the loudspeaker seems to play only a minor part in forming a person's opinion.

L.L. Beranek, Acoustics (McGraw-Hill, New York, 1954), p.208.

I hope you didn't mean that it's power of my imagination that poorly manufactured and skew food plate put on loud playing speaker vibrates and makes noises like waiter with shaky hands and tray in busy restaurant:D

I was told by a colleague who was into HiFi that there was a piece of audiophoolery which started as a prank in the 80's.

Someone placed an innocuous little ad in a HiFi magazine to sell a miracle fix for hiFi equipment.

It was a square of a 'special' material that you placed under one foot of your turntable to improve the sound.

It got reviewed positively by the high and mightys of a couple of HiFi magazines and sold like wildfire, helped by the price, it was less than £10.

Until the inventor outed himself and told everyone he was selling squares of plastic cut from garbage bags to see how gullible people were.

Even after that he still received orders and positive testimonials.

There may be a grain of truth in the fabric claim if the fabric is large enough, different wallpapers make a surprising amount of difference to the sound, I don't know if it's better or worse from a technical point of view, I just know from personal experience it makes a difference. (I may not be able to hear the difference any more as I'm 25 years older.)

An utility pole. It will certainly sounds better now...
Actually, if I were him, I would also buy a LISN for the amplifier..

Not at the least. But it is the power of imagination as to what that means. Surly sans the rattling plate the Stradivari will stand out more. But is that important? A Stradivari is still a Stradivari over AM radio. Sure - not clean sounding. But it is still Yehudi Menuhin playing a Stradivari.

But for these guys, a pole made them cry. That is an emotional response - and may not be rational.

I think, we should sell him a power plant. Pure and clean energy with fine tuned electrons for the best audio experience he ever had.  >:D

How about a solar system with dual battery banks.... charge one and use the other.  Feed power to the HiFi through a linear pure sine wave inverter - or, better still, rewire the sound gear to run directly off DC.

"The only way to *really* achieve what he's aiming for would be battery supplies ..."

A dedicated generator powered by a motor off the dirty grid.

Basically, his own electric utility.

Not clean enough.

Ask the people on the metalworking forums, apparently you can see the effect of single phase motors on fine metalworking, apparently they leave a 'swirl' pattern on the finish, a three phase motor gives a better finish, I would imagine you could make an audiophool case for that 'pattern' being transferred into the sound.

No, it has to be suffciently expensive. A PV system with two battery banks is nice, but too cheap. Maybe it would work with some audiophoolery solar wiring (US$2500 per meter).

You should consider electro-chemical noise of batteries.

I've been fighting these audio crack smokers for years but this one really takes the piss.

Edit: a friend of mine bought some stones to tape round his interconnects because from some crazy person. It goes THAT deep. Here I am with the shitty plastic RCA leads that came with it and I'm the mug apparently?!?!?!

Edit 2: seriously considering registering audiobollocks.com and dealing with this.
