a/v processor

Thinking of replacing Mcintosh 122 a/v processor.  Need some help on brands and models to meet my needs.  I live in Alaska so high end stuff non existent in the state, as is the tech advise.  I currently have basic 5.2 system with fronts driven Mcintosh 611s, to be replaced with Luxman m99us.  Center channel driven by Mcintosh 302 and rears driven by Mcintosh 452.  I have 2 subs.  Here is my criteria;
High quality 2 channel playback
Ability to decode all major formats, Imax DTS pro Dolby etc.
Superior DAC chip
Future HDMI 2.1 upgradability 
Anything other than Audisey room correction.  
More than 9 channels.
All advise suggestions welcome.
Thanks
