Summary: I can offer a qualified endorsement of this receiver. My experience is limited; my old system was an all-in-one; my new system, of which this receiver is part, is built of dedicated components.
Pros: Many inputs, internet radio (requires ethernet connection, which also enables direct firmware updating), USB input, decent power for modest configurations. 5+1 and 7+1 surround support.
Cons: ARC HDMI connectivity requires obscure setting to enable even after cable's connected to TV and receiver.
Summary: I finally retired my 15 year old receiver and after extensive research of features, prices and reviews I came upon the Denon AVR-400. I have only had this for two weeks and I am very pleased with the sound, features and flexibility this unit offers.
I love Denon products and have been using them for years

Summary: I love Denon products and have been using them for years. The one major issue I have with this unit is if you are listening to something like internet music and then use a universal remote to watch (change it to) something on the television - the image will not appear.
Summary: It has been a long time without a receiver and so it has been fun getting this set up. It has many more capabilities than I will use anytime soon but it does everything I need and then some.
Pros: Very easy to set up. Remote is simple and uncluttered Good sound. I like that you can program a limit to the volume and a volume level for when it turns on.
Cons: I wish you could define your own shortcut buttons on the front panel. I will never have a game system so this button is wasted. I would prefer a knob rather than buttons to tune the tuner. The tuner memories is not as fluid as I would like.
Summary: very easy to set up. was disappointed in Airplay output and could not adjust speakers individually without turning off the auto function. OK considering the price but will return it and keep looking at other options.
First of all great service from Amazon and the vendor

Summary: First of all great service from Amazon and the vendor. Receiver was easy to hook up and calibrate.sound is absolutely incredible no lie. no need for Wi-Fi because it plays music through my AppleTV easy breezy.
Summary: Overall this receiver is very good with many powerful features. The sound output just using a center channel and two side channel speakers is impressive. I use it mainly for TV, DVDs and Blue Ray Discs but do plan to try connecting FM radio and MPEG players as well.
Pros: Great sound plus Plenty of power and many features. The built-in sound optimization software was helpful, it detected that my speakers were wired out of phase ("Polarity was reversed"). The Crutchfield Tech Support was quite good and helped me with several set up problems.
Cons: I found it somewhat difficult to set up. There is no input for TV through antenna. To get the sound to play when watching TV required changing some obscure settings. I could not have done this without Tech Support. The built-in sound optimization software reported an out-of-phase error after I co...
Summary: So far, so good. Looks great. Sounds great. Easy set up. Does what I wanted to do for a great price. By the way, the Crutchfield people are amazing to work with. Couldn't be more helpful and friendly.
Pros: Looks great. Sounds great. Easy set up.
Cons: Runs a little warmer than I would like. I've only had it a couple of weeks. Hopefully that won't be an issue down the road. I do have it well ventilated.
Really a great addition and replacement for my Yamaha for home theatre

Summary: Really a great addition and replacement for my Yamaha for home theatre. The OSD for speaker setup and calibration of surround sound was so easy my wife could have completed it. I use the second zone for the speakers on my back patio with plenty of amp.
