Excerpt: I like the sound of my AVR-4520CI but am disappointed that the HDMI switcher in the refurbished unit does not work. I ended up purchasing a SC-77 after 6mo of troubleshooting without resolution. They should have just sent me a new one. Now it's just sitting in a box in the garage after spending $2k for it. I think the Denon sounds better than the Pioneer.
Excerpt: I've had my Denon 4520CI for over 1 year now, Nov-2012. Bought it locally from brick-n-mortar store AVIO in Michigan. It is used in my basement dedicated HT - dedicated room with 2 rows of seating for 8 people, prior I was using a 4308CI since 2008. The full suite of features and ability to manage my HT is key, this AVR delivers! Rock solid, I've had zero issues with this AVR and highly recommend it to anyone looking for top tier AVR to handle their HT needs.
Excerpt: I love the 4520!! The sound is superb, it just missing a few things that either older denon models had as well as lower denon models have. i.e..the ability to pause MP3's without having to completely stop and start over again. Also, the ability to rewind and fast forward streaming MP3's songs without going to the previous or next song. Another feature I could do on my old 4306 model was to pause streaming internet radio stations as well.
Summary: This unit has plenty of inputs, 4 zone outputs, 9.2 speaker (amped), four ethernet ports, and is great for future expansion I may acquire. It powers my Polk/Infinity speaker setup well. Setup was relatively easy using the "assistant." I have had significant issues with streaming via Apple iTunes / AirPlay while using the Denon free app to my Zone 2 setup. It seems like the unit resets its amp settings from 5.1/Zone2/3 back to 9.2 randomly.
Pros: Input variety, power, sound
Cons: Guided setup is limited, GUI not the best, AirPlay / Apple integration not the best
Summary: overall it's a great home theater receiver, but i find it quite annoying that the remote cannot send commands to a peripheral without also powering on the receiver and switching it's input to the particular device. (Compare: Okyo's "mode" button allows you to control peripherals without changing receiver input or turning receiver on!
Pros: sound, power/flexibility of amplifier section, number/variety of inputs, speed of DLNA response, HD radio support
Summary: I had a customer who recently purchased this RCVR, it is amazing except the following.... 11.2 only works if you run 2 speakers out to preamp, the RVCR is built with only 9 internal amplifiers. Also, if you want to use a zone, you are subsequently dropped down to 7.2... Same issue, it uses 2 amps to output to the zone, so you are left with 2 less in your main zone. So if you have 11 speakers in your main and a zone you want to use you can't do it all with just the Denon.
Summary: Bra ljud, trevligt med NeoX och 11-kanalers surround. Nätverksfunktionerna är katastrof, spotify crashar med jämna mellanrum. Både mobilappen och webgränssnittet är extremt slöa, nästintill oanvändbara, samt har en grafisk layout som en gammal geocities site.
Summary: Vorbemerkung: ********** Als Heimkino- und Surround-Fan der ersten Stunde habe ich schon einige AV-Verstärker/Receiver besessen und mehr oder weniger alle Evolutionsstufen in diesem Bereich mitgemacht. Anfang der 90er waren es ONKYO Geräte, später ein SONY und ein PIONEER, seit einigen Jahren bin ich der Marke DENON treu. Der AVR-4520 ersetzt bei mir in Verbindung mit einem DBT-3313 eine Denon-Kombi aus AVR 4310 und DBP-2010. Was ist neu, was ist besser?
