Is there an amp that does 2-channel and all this?

To clarify:

The HK-990 is a two channel amp with a 150 wpc power amp section derived from a Matti Otala (Citation, Electrocompaniet) design. It adds all the DSP functions that the OP has identified. NAD has a new one that is similar, but does not provide auto room EQ - as best as I can tell from their description. There may be others out there, but these two seem to be unusual in that they combine high quality stereo power amp sections with HT style DSP in the pre-amp sections.

If you're gonna use the DSP functions for music (As I do), separate systems for music and HT don't really work.

One more clarification, if you use subwoofers for music listening (as I do, and, apparently, as the OP does), digital bass management can be extraordinarily satisfying. Obviously, this idea won't appeal to the traditionalists out there, but after trying both approaches (I switched from ARC and Joule preamps to my Onkyo pre-pro) I'm a convert to Audyssey.

Again, YMMV.

I agree with Marty. In my system, anyway, bass management and Anthem Room Correction trumped HT bypass. But it completely depends on your room, speakers, etc.

I do have subs and I would like the crossover option. I am a fan of JBL digital correction for music. I have lots of speakers that I juggle around so flexibility and options are a plus to me. The HK990 looks like my best bet...

except...

If a dedicated 2-channel integrated like the Bryston 60R / Arcam A38 is going to blow any receiver out of the water then that is what I would get and worry about bass/correction later.

What to do!

I can't speak to the Bryston, but I can assure you that the Arcam A38 most definitely will not blow the Arcam AVR 600 out of the water.
