Yeah, if you're doing HT, try to keep the quality all around! Ideally, same speakers all around, or at lest up front. Also, for best sound with those Joseph Audio's, make sure you either sit close enough(as in small rooms) to the speakers, so as to hear mor "direct sound", or make sure of acoustic treatment considerations, sure of ceiling treatment!
The reason I say this is those "open architecture" traditional "tweeter on top" designs tend to make you hear more ceiling interaction and floor interaction! Doing what you can to ensure a higher proportion of direct sound vs. reflected is critical for best detail, dynamics, soundstage acuracy and imaging, as well as dialog intelligebility.
As for processors, I don't think you're getting anything by going Theta. I never thought too highly of that processor line for movies. I sold both Classe and Threshold, as well as Krell, Meridian, CAL, Integra, and other higher end pre/pro's. I don't think the Theta has anything on your Classe. I think, at very very best, it's a sideways move.
If you like your overall sound, I'd stay put there.
