erik, Roon core ran on a Mini downstairs on a MESH network. The router and QX-5 are upstairs and were connected to a MESH node via Ethernet cable. Both now connect directly to Ethernet. The QX-5 takes in Ethernet and outputs balanced analog. Call it what you will.
A Pi4 needs a DAC. The QX-5 is an excellent DAC. The ultraRendu downstairs uses an Ayre QB-9 DSD DAC, another excellent DAC. The Pi4 would replace the Nucleus, not the QX-5. I suspect the DAC is where the magic happens.
The QX-5 is doing a lengthy OS update now, and I assume once that is complete the QX-5 can be enabled. The Bryston SP3 HDMI has been enabled.
