I bought the DPR 1001 on impulse and i must say it was impressive. The surround processing is excellent. The only problem i had was the amp is only 50 watts per channel. My speakers are highend and demand power. It clipped out during some intense scenes on dvd. They're introducing the DPR 1002 which will have 100x7 later this year. The remote is nice. However i did have a problem with swithing functions dvd, dss, vcr, etc. The remote kept defaulting to AVR. All in all a good receiver for a room like yours. You will be impressed. You can get them for 585 at etronics. I returned it because of lack of power. I bought the Marantz 6400. Better quality components and more power and of course a little more money.
the H/K DPR-1001 differs from the rest of the H/K line in that it has IC outputs, rather than transistors. This means it runs cooler and and is much more economical for H/K to build. On the other hand, it has higher distortion and no dynamic headroom. This is why Kal suggests it lacks power. It isn't that it is 50 wpc. If you were to compare a 50 wpc NAD receiver (the T742 which you can get for $449) to the DPR-1001, you would never believe both were 50 wpc. The NAD is capable of much more clean sound because its transitor outputs can actually put out much more current to the speakers.
In my opinion, almost any good transistor output receiver beats an IC output receiver because they are much more dynamic and cleaner. Marantz is a very good alternative.
