“I’ll still maintain the most beneficial network improvements come post server, which means two computer setup, aka separate server feeding usb renderer/roon endpoint/streamer.”
I respectfully disagree. There are other streamlined options to isolate the noise without ‘cluttering’ your space. Choosing a good server or streamer that specifically designed for audio is fundamental to the approach of clutter free streaming experience. Once you get that out of the way, then you can focus on DAC and noise filtering devices.
