Tested EtherStream in my friend’s system consisting of expensive cables, Odin 2, CH Precision with PSU, Trinity pre & power amp. Compared to the stock Cisco switch (same as EtherStream’s stock Cisco except 5 ports), major and clearly audible improvement.
In my system with Nimitra Music server with all Vitus Masterpiece components, there was improvement but not as dramatic as in my friend’s system. Probably because his NAS was connected to EtherStream where else my SSD was connected directly to 1 of Nimitra USB port.
I did compare it streaming through Tidal. Even though it better compare to using stock switch, I prefer the SQ streaming through local files. How good is Nimitra? Not bad at all considering the price. I used to play with Aurender W20 connected to MSB Selectl. For reference.
This is just my opinion. Couldn’t believe a modified switch can make such an impact on SQ.
