Of course, you can pick up an MC-1 or an AVP for less than $3K used now, with new models coming out, and the HTS2 is $6500 retail without many on the used market yet. Right now, without extensive auditioning, I'd want the HTS2 too, but you have to factor in the cost.
I also have to balance out the notion that the MC-1 sounds "horrible" in two channel stereo. I own one and I certainly wouldn't describe it as "horrible" - in fact I think it sounds pretty darn good. Coupled with the fact that I really love HT and it's equal to the best in sound for movies, I think it's a fabulous piece. Anthony Cordesman, when reviewing it for Audio magazine, found it to be a fairly excellent stereo preamp, and I have as much respect for his reviewing as any reviewer going. Is it the best? I seriously doubt it. But for < $3K used and all it's versatility, it should certainly be a contender for somebody wanting a pre/pro. -Kirk
