I've just ordered the Aperion 5.1 speakers and waiting for them to be delivered. Meanwhile, I'm shopping for a receiver and was in CircuitCity comparing the HK AVR525 and HK DPR1001. For movies they both sounded pretty good and almost the same, I'd adjusted the db levels such that they both produced same "loudness". But for music, the DPR1001 had a nice little additional base to the music (with the same setting on both receivers and the same set of polk audio floor standing speakers). I'm planning to checkout the Denon's but it looks I can't compare the HK and Denon in the same store (I didn't see Denon's in CC and didn't see HK in Tweeter's). Does anyone in this forum have a personal experience of comparing the two (HK AVR525 and AVR1803,2803)?
