Ethernet and USB cables


Do premium Ethernet and USB make a sonic difference? I have very good speaker and DAC to amp cables but, all the others are just inexpensive generic cables. I’m running Innuos Zenith MK III and about to try out a Phoenix USB. Just looking to get the most out of the system w/o throwing away more $ (unless it works!).

Bits is bits as they say.
Put in any old cable.  Measure the error rate.
It will max at about 2 or 3 per million.
The other 999,998 will come through perfectly.
You can't hear the two that don't.

End of answer, apart from dither and clock error that are not products of cable, so far as I know.
p05129 what may seem odd to you is not to others. My claim to have some good cables is based out trying different ones but, I haven’t tried other USB or Ethernet cables. I was hoping to minimize that process and I thank everyone who has helped by sharing their experiences. This is a great forum because I’m getting feedback from so many audio fans.
I haven’t tried super high end Ethernet cables but can confirm that Supra cable is a clear and wonderful enhancement over generic Amazon cable. And it’s cheap as far as cables go (I think 55ish for a short length).

I have more than I need so will be listing here or the Mart when I get around to it.
@clearthinker,

for the umptiest time: it isn’t the errors in bit transmission but rather spurious EMI/RFI or ground level noise travelling alongside the bits and messing up the d/a conversion that good cables can address.
