I have heard significant improvements in sound quality by adding the following to my Ethernet set-up:
(1) An English Electric 8Switch after a 50-foot run of BJC Cat 6a cable coming from my router.
(2) The high quality Network Acoustics streaming Ethernet cable connected to the switch
(3) The Network Acoustics ENO filter, with its short built-in cable coming out of the ENO and connecting to my Innuos server/streamer.
This configuration is very similar to the pre-streamer approach described by @audioengr earlier in this thread, but I am using a different network switch, different Ethernet cables, and the ENO filter rather than the EMO isolator. I directly compared the isolator to the ENO filter in my system, and the ENO filter was significantly better at removing harshness and noise while allowing realistic high-frequency "life" and "sparkle" to come through. Other network switches may be a bit more or a bit less effective than the EE 8Switch in improving sound quality, depending on the cost/design of the unit and the power supplies used. As usual, cables matter, too, but the Network Acoustics streaming cable is an excellent cable and has worked well for me.
