No server or streamer is ‘completely’ immune to noise being transmitted through your mass produced routers.

the inherent noise issues associated with streaming.
Just to add balance, there are many network knowledgeable people who do not believe there is an "inherent noise" associated with streaming. Keep in mind these types of beliefs sell products, just like dietary supplements and copper bracelets.
Not saying none of it has any effect. But caveat emptor just like everything else. Audiogon isn't immune to mythology.
