In anticipation of trying this I purchased a Motu AVB switch...
Interesting, I'll be interested in your experience with this setup as it evolves.
Similarly, in anticipation of a network based solution, I foolishly sold my OR5-HDMI and installed a D-Link DHP-701AV Power Line Ethernet connection. I was able to get about 170 Mbps over the power line into my basement listening room but hard telling how much noise I have introduced to the rest of my system. I'm running Roon off a MacBook Pro in my listening room with a Revelation Audio dual-USB cable into a W4S DAC2 DSDse. The MBP is connected to the ethernet (for internet and remote commands) with WiFi disabled. Eventually I anticipate moving the MBP upstairs by my router and having an Ethernet renderer feeding my DAC.
Anyway, I really like the Roon interface but my sound quality had taken 5 giant leaps backwards.
Oh, and one of the reasons I sold the OR5 was to do DSD, but DSD (DoP) over USB into my DAC sounds like someone threw the proverbial wet blanket over my speakers. Double
So I guess I will wait to see how this technology evolves but for now I'm going to be listening to vinyl...
