@soix I assumed it was a common feature and because I currently use the STR and am adding the AVM 90 and both have very good DAC’s. I use Home Theater Bypass on the STR stereo preamp and share the FL and FR mains and two subwoofers. It would be nice to use Zone 2 on the 90 for music playback on our whole house system and if I learn to burn multichannel SACD’s and a streamer supports it, I might eventually want to take advantage of it.
I do like a lot about the Innuos Zen MK3 you linked to.
Thanks.
