@emergingsoul @cleeds I prefer hard-wired too but some people don't have the option.
Networked audio is one of those unusual areas in which you're really not better off solving a problem at its source; it's better to address noise as close to the streamer as possible. Whether a switch used for audio is "audiophile" or not is actually less important than where it is! If you want to use it to kill RFI noise, rather than as a port replicator to give you more ports, it needs to be the shortest possible length of cable from your streamer (say 1ft to 3ft).
The switch-streamer cable should either be unshielded (like Cat 6) or ideally be known/measured to have the shield grounded only at one end (there are precious few of the latter); most big name audiophile cables and Cat 8 (it's part of the spec) have in common that the shield is grounded to both plugs and this allows RFI stopped by the switch to travel down the shield and reach the streamer, exactly what we don't want.
