I had read numerous positive reviews on audioreview.com about the Denon AVR-4802 before I purchased one. Many of them raved about the improved 'sound imaging' of the Denon when compared to their former receiver or amplifier. When I got the Denon I hooked it up to 7 speaker + subwoofer system (which was +2 speakers from my 5 speaker + subwoofer sysem). I noticed an immediate huge difference in the sound dispersion on movie soundtracks. In Lord of the Rings there is a knock on the door of Bilbo's hobbit hole in the first Shire segment and it with the Denon I almost got up to answer MY front door. There was a big difference, quite noticeable between this new setup and my old Sony DA555ES receiver. Is it the Denon or the two additional speakers? One thing is certain: the Denon sounds noticeably better a number of ways. Stereo listening is fantastic. Kind of like my old NAD receiver but with a lot more power (125 watts x 7).
