Summary: Great sounding reciever. Was underwhelmed at first coming from a Harman Kardon 2650. I Only upgraded to be able to bi amp my polk rti10's. Big difference in power and features. The Audyssey multi xt32 takes very careful calibration and is very important to have the correct 8 point mic placement and to make sure there is absolutely no background noise or anything running in the background like central air or refrigerators, and ceiling fans.
Summary: I bought this because I wanted 9 channels of sound I utilize this in the conventional 7 speaker setup with front height I have two subwoofers and like the fact that this has Audyssey xt32 which give substantial improvement to how the subwoofers work in the environment I own two other denons one with Audyssey MultEQ and the other with Audyssey multi XT, Audyssey xt32 makes a substantial improvement for the subwoofers however I did not find as much as an improvement with...
Summary: I am comparing the Denon AVR-4520 to my Yamaha Z7 receiver($2600.00 retail), and my Krell AVR300 Receiver($3500.00 Retail). Sounds much better than the Yamaha, and is equal to the Krell!. Easiest setup I have Ever Seen. Audyssey MultEQ XT32 Room Correction far better than Yamaha YPO. Music Blu-rays sound much better on this receiver. Very Pleased with my purchase. Adorama service was perfect! I am a happy customer.

Summary: Awesome! I have a AVR-3310CI (150W + Audyssey MultEQ) and thought the sound quality between the 3310CI and this 4520CI were about the same given I am using just a set of OK speakers (Polk Audio VM20 + DSW microPRO 1000 subwoofer) and my non-professional ears. Boy was I wrong! Music, songs, movies become LIVE! Suddenly, my favorite music and movies become from great to awesome!
Summary: I picked this model up after research on the web, and after several days am very impressed. I've owned several receivers previous to this one, including 2 flagship Onkyos( 876 and 906) and a Denon 3803. This receiver sounds better than anything I've encountered in a receiver. I'm a bit of a purist, and don't need some of the highly technical features this unit has, but sound quality counts alot, as does functionality. The 4520 has both in spades.
Summary: OUTSTANDING!!! I replaced a Yamaha RXV861 with this and it was a HUGE upgrade. The XT32 room correction lives up to the hype. Light years ahead of the YPAO I was using. Sound is so smooth and detailed, I went from thinking I should upgrade my speakers to thinking that would be a waste of money! It has improved EVERY aspect of sound quality in my system. From dialog to details to surround effects to bass. I have never heard my surround speakers sound so good.
Summary: I got this receiver for a fraction of MSRP and this receiver is a beast. I upgraded from HK avr 3700 for mare channels. I did not feel hell of a difference but Denon sounded better (of course it's twice the cost). Plenty of features and nice app.
Summary: I recently upgraded from a 12 year old Denon 4802 and couldn't be happier. I removed my rear surrounds and now have 9.1 with height and wide channels engaged. The soundstage is amazing. Very pleased with the purchase.
Excellent receiver. Big improvement over more recent Denons.

Summary: I used to be really into Denons AVRs. Had several units in pre-HD days and my most recent one before this 4520CI was an AVR-2805 that I loved. Then came HDMI and after having handshaking issues with Denon's initial offerings, I looked elsewhere. Enjoyed an Onkyo TX-NR905 for a while then replaced that with a Yamaha RX-Z7. Both were great.
