You probably won't like the answer, but I haven't found a processor that really sounds good in 2 channel audio and I have tried several of those listed above. My thoughts are to purchase a processor that you like for its features, codecs and ability with theater and has a pass through for a good 2 channel preamp.
I am currently using the Onkyo Integra 9.9 which does what I need in a theater processor. It also has a pair of balanced inputs on the rear that can be set as a simple pass through with no processing.
My Analog goes into an Audio Research tube preamp which again does what I need there. I then feed the output of the ARC preamp into the pass through of the Integra.
Everything even works with the Integra remote control. Push "Receiver" for theater and push "Phono" and you have the ARC preamp. Set the volume control about half way on the ARC and then the volume is controlled with the Integra remote as well.
I'm sure there are other ways to do it, but keeping the Analog and Theater separate but still in the same system makes for really great sound.
