Sounds amazing!

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. Read more

Was ok while it worked.

I have Vienna acoustic speakers and this system couldn't handle 4 ohm speakers. It stopped delivering any sound or video.

Comparision vs. Denon AVR-4311ci

By kamiraa on November 10, 2012

I think a lot of people whom are considering this class of AVR are coming from last generations 4 series (avr-4311ci), so this review will cover differences for those people.

FOR those who DON'T currently own a 4 series, let me just say it's an amazing receiver, IF you are building a serious theater room or listening area it's WELL worth the money (relative). It is one of the very few receivers that can handle 11.2 channel DSX and with it's additional capability, features, and quality it is truly currently the king of all receivers in 2012.

FOR AVR4311ci Folks:

First off, the amplification circuitry looks to be about the same, same power ratings.

They tweaked the Audyssey even though Denon claims they didn't, because I'm getting significant different results from my AVR-4311ci in the same room, same speakers, same everything. They tweaked it for the better, because everything sounds to blend perfectly, and the eq's records dead on once I mic'd the room using an external source. AFTER enabling the XT32 results and the response curve is perfect. This is to verify for the folks out there, LEAVE the Audyssey XT32 EQ on, it works PERFECT, I'm hoping my extra steps of measurement will save you time in your setup if you question what it's doing. Just make sure to perform Audyssey DSX property and use all 8 listening locations as it is measuring the acoustics of the room NOT seating locations. Even if you have a single chair in the room, use all 8 locations to measure the acoustics around the room per Audysseys recommended locations.

I had to adjust the levels of the surround speakers and sub since I always consider those levels too low for my taste (a preference thing). The EQ remains in tact with these manual adjustments.

Excellent receiver. Big improvement over more recent Denons.

By Lars Milano on December 15, 2012

Verified Purchase

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. I purchased, tried, but eventually passed on a few Denon models at the time and went for these alternatives simply because in my opinion, they were overall better receivers than Denon's when I factored in sound, feature-set, and overall connectivity ease. While HDMI is still a pain to this day, some receivers handled it better than others.

Recently, my home theater needs have changed and I wanted a more current model that supported the latest fads and gimmicks. Happy with my RX-Z7, I initially decided to step up to another Yamaha, the RX-A3020 from their flagship Aventage line. Fantastic sounding receiver, typical of all Yamaha AVRs I've experienced, but with one big flaw: the HDMI handshaking bug existed in my unit. Without getting into too much detail with that issue, I decided to return the Yamaha and try others. Ordered a Denon AVR-4520CI which showed up DOA after likely being dropped several times by UPS from the damage to the box. This first shipment was not double-boxed like Amazon normally does and the result was apparent shipping damage. Since I was on a roll with my AVR misfortunes, I decided to order several other AVRs so I can try them all out. Ordered another 4520CI from Amazon, and a Marantz 7007 and Onkyo 5010 from another vendor. All arrived in one piece and after a week with these units, one came out clearly on top: the Denon AVR-4520CI.

Beware of service delays

By Dr. Talk on January 21, 2013

Verified Purchase

I got the Denon AVR-4520CI at Christmas after doing MONTHS of research. It worked as expected for almost a month. I had to reset the processor one time, but no big deal. However, not 30 days into ownership and it decided not to play audio from components or within itself (AM,FM,network). Called Denon and they were quick with a service tech to listen to my issue. We spent 40 minutes on phone trying to see if the problem was external to the unit. It wasnt. Now for the kicker...I live in Georgia and they have one authorized service center, though not too far from where I live, the service center said it would take at least a MONTH to fix the unit. I checked around, even discussed shipping to authorized service centers in other states. All were pretty much slammed and said the same thing. If Denon wants $2500.00 for a unit like this, they need to step up and get more authorized repair centers to do warranty work. I have had this unit less than a month and it is going to spend more time than that in the shop. Not good.

Disappointing reliability

By A. Raffel on December 11, 2013

I really would like to give this receiver the highest praise, but: I can't.

It is great when it is working, but it has not been working enough hours/days since I owned it. Meanwhile I am on my 3rd replacement (all under warranty), AND an additional 2 repairs. All this less than 6 months after my initial purchase.
I just received it back from the latest repair, and it worked fine for a week.

Now it switches the sound off because it seems to detect headphones (displays "H/P input on/off): this switches randomly within seconds forth and back. Usually sound is lost for minutes.

I am not even going into details of the previous problems with green screen, faulty ethernet panel, ...

Again, if working as designed, I'd give it 5 stars. After all my trips to the repair shop, a 3 star deduction is warranted.

Update: I was so annoyed with the reliability that I felt compelled to write a letter to Denon. Customer service has responded with the best case scenario: the next problem means I get a new unit (originally I had purchased a refurbished one) and my warranty is extended for another year. I'm going to add another star because of this.
