Summary: Sound: great quality, great user interface, nice features with iphone app. only negative point is the lack of a second zone - ie for outdoor speakers, or at least a sound out for a second amp..
Summary: I went from a fairly expensive Denon receiver to this unit and the change in surround sound through the same speakers was dramatic. The setup was a bit complicated due to the process of fine tuning the speaker output algorithm with the provided microphone. Although fully setup the sound produced is amazing.
Summary: The seller Worldwide Stereo ran out of AVR1913 so they sent E400 new model to me. Thanks! E400 is more than what I expected. My need is to connect audio speakers (no tv) and I didn't want the box with wires in the living room. With Denon iPhone app and E400 connected to network I can power on, off, and play songs without having E400 in line of sight and physical remote. Second E400 plays local and international radio stations off Internet.
Summary: We all know that trying to extrapolate true power ratings for five or more driven channels simultaneously can be an exercise in frustration at times. 90 WPC stereo 8 ohms measures around 70 WPC according to the Home Theater Magazine review. I knew this going in, but still wish I had bought more power going in. I haven't had clipping issues to date, and it is capable of playing at SPL that I probably shouldn't, but still, there is no such thing as too much power.
Pros: REasonably. 7.1 capable. Good price (on sale). Clean sound. Audyssey works well. Intuitive menu system.
Summary: The receiver I got works and looks like new. The only thing that was missing was the little piece that goes over the front connection ports (not a big deal to me). I would recommend. Also, this receiver has a 1 year warranty from Denon, not a 90 ...
