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

A $4000 Arcam or NAD or Harmon multi-channel receiver is still going to sound crappy compared to a $2000 2-channel integrated amp.

The 2-channel guys have just opted out of responding to this thread just like most vinyl guys don't bother trying to answer the question "What DAC sounds like vinyl?"

I think you'd be better off getting a 2 channel system separately from your HT system, and finding a way to integrate them (usually, say by using a HT bypass option found on some preamps or integrateds).

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!
