Yep, Trinnov processors aren't cheap but neither are 7k and 8kSEs which would probably be in a system of that calibre. The point I was trying to make is that M's new interface adds very little to the cost % wise.

There's also the Altitude 16 to consider but this doesn't have digital outputs from what I've seen so it would be an analogue connection to the 271.

Main system - Sources (Kodi-HTPC, Vero 4k, FireTV, Sat) into Trinnov Altitude 32 (8-16) (+Roon), Trinnov Amplitude 8 amp & Vivid Audio (Giya G3, V1.5) and REL Stentor III speakers. Others: F80 + Raspberry Pi and other Pi systems.
