My issue with switches for anything other than convenience is its simply not accomplishing much. So you have this noisy modem and router upstream of switch, the audiophile switch there to isolate downstream components from that noise. Ok, I get that, the issue is the streaming chain has already been contaminated from the noisy modem and router, you're only treating the symptoms vs the disease with the switch. A much better route is to treat noise at the source, Broadcom chipset vs Intel chipset in modem, disable wifi on router, emi-rfi contamination, power both via lps. Beyond this get rid of router altogether vs something like Dejitter Switch X, this a switch with capability to assign IP address so wifi can be offloaded to second router with wifi enabled to service rest of house. So now you have a 'clean' or audio only network in house, simple and clean setup. And for those who don't believe networks have any sonic impact, you're welcome to your viewpoint, but this not the case.
In any case, the above optimizations come only after first addressing streamer and dac, this for very mature, high resolution streaming chains and audio systems. Many other more important things to address before adding some fancy switch.
