Summary: This is a great receiver, but one must be a whiz kid to get the thing hooked up correctly. Apparently, Denon is not known for its ease of use. Once hooked up right, the sound is great. WARNING: if you have an early Blu-ray player (i.e. 40gb PS3)you will not be able to play bit stream allowing the very best sound. Instead, you will have to use the linear setting to get your TRU sound and DTS, and the functional lights on the receiver (dts, TRU, etc) will not light up.
Summary: I am still having mixed feelings about the AVR-591. Now that I'm used to it and was able to solve its most frustrating problem (requiring reset every day, discussed below), I decided to keep it but hope to solve its remaining weakness (remote control weirdness) with a Harmony at some point.
Summary: Since "7.1" turned out to be a waste of time and money.......7 channels is mostly a waste, since they don't mix 95% of movies (even the new Blue Rays) in anything but 5.1, it's all fake data and doesn't sound much better than just 5 channels. This no-frills approach from Denon is exactly what I needed for my second, smaller Home Theater system.
Summary: UPDATE - MARCH 25 2013 Everything keeps working fine. Still happy ORIGINAL POST 2011 I'm very happy with denon avr 591 receiver. My first receiver was a samsung, included in a kit (home theather in a box). The difference is big. Sound quality is great. I'm using jbl control 1 speakers in front and for surround. Center speaker is from the old samsung ht, and old subwoffer didn't work with this receiver. Any way, sound is already very good.
Summary: I am not a specialist and this is my first A/V receiver. NEvertheless, this device has what you need to have with modern equipment : 3D, 4 HDMI (1.4a which is necessary for 3D), etc. It also has a mike to automatically configure itself. It is quite easy to use and has sufficient features for normal non-professionnal use. A very good deal at this price.
Summary: The wife and I bought this receiver mainly to simplify our home theater setup by having all AV inputs fed into the receiver via HDMI with only one HDMI output to our 50-inch Panasonic LCD HD TV, and I must say sound and picture quality from all input sources of our home theater system are first rate with the Denon AVR 591.
Summary: I bought the Denon AVR-591 to simplify my home-theatre setup and so far it's working perfectly. The Quick Select buttons also power-on the unit and so my preschool kids are able to press just one button ('Quick Select 1') and get the TV to work. I was also able to reprogram our Logitech Harmony universal remote so that it sends fewer commands.
Very good basic receiver but at higher price a little bit
