I would suggest that you get a processor that sounds good for HT and multi-channel music, and get a separate 2-channel pre-amp with a HT passthrough for 2 channel critical listening. You can find a good used 2-channel preamp with the HT passthrough that will sound better than many high dollar processors that try to do double duty. In my case I have a Krell Showcase and a Bel Canto Pre-2P and I am very happy with my 2-channel and HT performance.
Best Multi-channel amp also good for 2 channel
What in your experience is the best multi-channel (say 5) power amp that can also double duty for critical 2 channel listening?
