@oldhvymec Try reversing your expensive ethernet cable. They are directional. I experienced sharp edgy highs with my Pangea ethernet cables too, until I reversed them. Then they beat out (but not by a lot) my $7 ethernet cables. The Pangea improved the clarity a bit. Overall tonal balance was the same.
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!).
