OK, one step back I think.

What I want:
2 channel, with MQA if possible. 5.1 with G65 capabilities incl. Calibration, Bass Management, Room Correction, MCP, etc.

Gear:
As my signature. MC200 is backup, Tidal Hi-Fi, RoonServer on Mac Pro (wired).

Current wireing:
All speakers connected to G65. SL Slave from 218 to SL In2 on G65, assigned to CD.

Cuurent status:
It`s working fine, except no MQA light on 218 and volume on Roon Remote is not working.

Comment/question to Gianni proposal:
When connecting mains directly 218, would I not loose playing 5.1 with G65 features? If no, is G65 (or 218) merging speakers from G65 and 218?

I this clarifies.

Cheers,
Frode
