Audiophile Ethernet card! Finally!
« on: July 21, 2017, 07:41:06 am »
Finally, I can listen to the Internets properly!

http://jplay.eu/ml_post_slider/jcat-net-card-femto/

Some highlights:
Quote
External PSU option

Even though there are ultra-low linear power supplies exclusively on the JCAT NET Card FEMTO, for best performance it is recommended to connect external linear 5V PSU (such as our 200W or 400W linear PSUs) as the source of power instead of using computer PSU.
Sure, why not?

Quote
• Industrial grade components with operating temperature range from -400 to +850
(gotta get me one of those -400 components!)

Quote
For customers who would like to purchase x2 NET Cards FEMTO (for Dual PC mode), the price is 800EUR (instead of 844EUR). Ask for the discount via email!
Awesome! Finally I can listen to the Internets in stereo for a discount!

Holy crap! The rest of the products are even more audiophilish!

Crystek’s Model CCHD-957 HCMOS CLOCK oscillator family has been designed specifically for High Definition
Audio (HD Audio). It features a typical low close-in phase noise of -100 dBc/Hz @ 10 Hz offset, and a noise floor of
-169 dBc/Hz. With this extreme low phase noise performance, you will “Hear the Difference”.

They probably lack the required documents and skills, but man these guys must be craving to build a x86 or ARM based computer with TCXO CPU clocks, linear CPU rail regulators and shielded memory bus interfaces.

And then amplify the price by preferably 50 times.

Don't let them go below absolute zero or you'll mess up the tachyon ordering of the bits and end up listening to the music in the wrong order.

If this accidentally happens, compensate by cooling your ears to exactly the same temperature.

By removing thermal noise directly from your eardrums, this will of course deliver a listening experience that you'll be totally unable to fault - something true audiophiles strive for.

I have, more than once, put forward the theory that dipping entire audiophiles in liquid nitrogen overnight would silence the spurious background noise they generate.

You should also check out their forums. A wealth of information laughs to be had.

Man, this would go great with my 1000$ HDMI lead so I can get the best video quality and audio quality.

SATA, ethernet, and USB cables are only 349 euros each. Bargain compared to that $1000 HDMI cable that may not even be 2.0b compliant(?).

This is just going to run and run...

For extra laughs go and read the websites for the products mentioned in said forum.

There's what seems to be a bottomless pit of golden ears audiophile BS to mine

I see a business oportunity here! How about a well tempered 300 baud modem, synchronized with a cesium reference (you don't want your bits drifting) and a 100W class A audio output with silver heatsinks and galinstan liquid metal cooling with magnetic pumping? A discerning audiophile must hear each bit coming in.

Ethernet allows almost endless extra audio tweak possibilities: dynamic vs. static IP, does 10.10.x.x sound better than 192.168.x.x, sound differences between router ports and what is the correct cable direction (twisted pair direction). And of course all the usual audio device tweaks also effect ethernet devices.  :o

 :palm: Will this ever end?

I can understand in an analog amplifier maybe having a better more rugged power transformer and better DC power caps, but, in this digital BS, the only part that matters is the DAC and it's clock in the analog output device.  Anything else would be a failure in broadcasting the error free digital data from point A to point B.

Funny, when I use my WiFi, filled with local interference and lousy clocking and noise, the exact same bit-stream reaches my sound card's output whether it was in the originating computer with it's HD, on an Ethernet cable talking to the remote HD, or on the WiFi doing the same, over even over the 'internet' where who knows, every other device in the link throughout the world wide web is guaranteed to not have audiophile grade components.

Same thing with power cables, the miles of cabling back to the powerstation seem to be conveniently ignored yet chucking a couple of metres of pure crystal aligned unobtanium BS fixes all that...

Yes, when there are no humans anymore ;)

Some people like to ignore the fact that data (including audio streams) is buffered if passing through networks.

Class A subnets will sound better of course!

Should hack the OS to use port 0 for audio streams, it has less digital noisy edges than say the very noise ports 21845 (5555h) or 43690 (AAAAh).  :popcorn:

Better switches and network cards may benefit the performance of an AoIP  network but the stuff in that website on OPs post is bullshit.

Odd, they look very much like Cisco switches with a new front on them, I wonder what the etch on the boards says...

*edit* ha, they are Cisco. So, not audio grade, 'just' enterprise grade.

Puny humans, how can you forget proper storage? Gotta store it on an audio grade SSD such as found in: https://www.audiodestination.co.uk/digital-64/digital-media/melco-audio-n1zs20-mk-ii-2-tb-audio-grade-ssd-high-resolution-music-server-and-usb-media-player-direct-cd-import  lest the electrons fall out of your music.

Why only a gigabit adapter though? They should've made a push for 100Gb. Gotta stream at maximum speeds so latency doesn't affect your music enjoyment.
