got the denon. just got it all hooked up and am testing it right now. listening to radiohead's the bends album.... wow! this was a serious improvement over my sony receiver! While the sony was great for some stuff, once I got my subwoofer i could tell it was meant for home theater, not music. bass was a low, low rumble regardless of the setting. it sounded like movie bass. i figured that's just what a $100 sub sounded like. but with the denon it really brought that subwoofer to life. sounds like it's supposed to, with some punch to it. it also sounds fantastic at low volumes with the use of the loudness control.

really happy with this purchase for $50, thanks for the recommendation!
