A discerning audiophile must hear each bit coming in.

And of course all the usual audio device tweaks also effect ethernet devices.

content: 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.

If you've experienced harsh sound with with IPv6, it's because of a completely detuned IP address not in balance with your sound environment. I'm working on an IPv6 audio tuner right now. It's similar to a guitar tuner and allows you to finetune the IPv6 address fast and easy.

content: I hope that takes Gbics so I can use audio grade multimode shielded fibre optic cable.If you patch it through an audio encabulator it will increase the performance even more but you want to make sure the far end is using a decabulator in order to componsate for the flex density of the wave matrix. Make sure you get an encabulator by GE directly as there are lot of fakes out there.

Everything else prior to the DAC along the digital transport pathway (USB, ethernet, etc...) should not be susceptible to noise, that's the whole point of digital, no?

But I just used an old sound-blaster card that I moved from PC to PC ignoring the onboard sound-card with analogue amplifiers sitting in the middle of digital busses. Have they bothered to come up with an overpriced shielded soundcard ?

Comments from any psychiatrists here are welcome, since there may be other aspects and explanations for the behaviour described.

Did sound suddenly get better or worse when I pulled the cable? Can you tell when the cable was swapped (no one could). Etc, Etc, Etc.
