I can see the logic to this and Ive read some nice posts on how the final connection is really the only bit that matters (unless data is actually being lost/dropped somewhere), otherwise on streaming services, you'd have to worry about the jitter-trail all the way back to hard drives in their data-servers for example.
Hmm... logic and hifi don't always go hand in hand!
I'm also not sure that ethernet provides most of the isolation. If anything I think ethernet can often be the problem. Hence the reported success of using an optical bridge - I haven't tried this myself but know of many that swear by this. Myself I have had great success using Entreq to "ground" (oh oh I can hear you all tutting!) NAS and routers...
Don't forget that Vincent at totaldac who is your ultimate measurements engineer has created an ethernet cable with a massive (ferrite) choke - this acts as a low pass filter effectively absorbing all the high frequency noise that allegedly travels down the ethernet cable. He recommends that this is used to connect switch to d1 server.
I think possibly one of the reasons that the Melco works so well is that it effectively replaces your network. All those computers/NAS/switches with their cheap SMPS...
So for me - at least - I worry about the whole chain from source to DAC and want to optimise every stage of this. It's certainly not scientific but it floats my boat and seemingly a few others.
