I have the Sony STR-DN1080 connected to a 5.1 system based on Q solutions speakers with 3050i’s as front channel. For music I am feeding Roon via a iFi Zen DAC into the CD RCA’s which sounds OK. I was thinking of getting a Musical Fidelity Msi2 as connecting it to the Zone 2 outputs and then conneciting the Roon endpoint directly to it via USB to its DAC. The Msi features Home Theatre mode which I think would allow it to be controlled from the sony for 5.1 and the Roon stuff could then just be 2.1 when needed. Question is can the Sony work in 5.1 when using both zone 1 and zone 2 outputs? If anyone has tried this I would be interested to know.
