In a setup where Roon core runs on a noisy PC, connects thru ethernet to a Cisco wifi router, and the optimized audio PC receiving from Roon on HQP also connects thru ethernet to the Cisco, would you recommend using just one EMO-EN70e at the audio PC input? Or more, or elsewhere? How about a linear power supply on the Cisco?
First of all, the only thing that matters is the router, not the PC. Don’t waste money on the router, it needs mods.
This is what will deliver great results, even with a Sonos:
1) AQVOX switch added to the router
2) 0.5m Wireworld Platinum Ethernet cable from switch to isolator
3) EMO EN-70e isolator
4) 1.5-2m Wireworld Platinum Ethernet cable from isolator to PC
