Short answer…. YES. I had them”usual” STAPLES grade CAT7 thinking that’s as good as it gets . I was not happy . So I upgraded to a CARDAS CLEAR and Avanti Audio Vivace CAT7 Ethernet Cable.
MY TAKE::
(1) A clear and unambiguous step,up, in digitsl audio performance for me MOON 280D MIND2 streamer / DAC. ( by SIMAUDIO)
(2) But don’t limit yourself into thinking this is the sole silver bullet solution.Rather, consider introducing an external power supply (iFi PowerX) to the Ethernet switch too. I was a non-believer and skepric too…until a friend brought over his IFI unit. = immediate step up in bass, slam, and dynamics along with a noise suppression.
who knew?
PS: we did a further bakeoff Belen 2 power supplies: the cheaper iPower2 versus the the upgraded iPowerX The iPowerX was clearly a bettter experience
