@jmeyers, how much are you willing to spend on a dedicated network switch? If price is no object then I’d definitely recommend that you look into the Network Acoustics tempus - Precision Ultra Low Noise Ethernet Switch. Rob Osbourne and Rich Trussell are some of the most considerate and attentive folks in the audio gear biz that I’ve ever dealt with. They both took the time to answer every dumb question and email from me no matter how ponderous.
I’m still using their now discontinued 1st gen eno streaming system Ag in my headphone setup, and I can only imagine how great their new stuff sounds.
In my experience with the English Eight and the SA Bonn switches, neither one had a better impact on the sound in my system than the Cisco SG 250 switch that I’m presently using in sequence with another readily available D-Link switch which I bought on Amazon.
