How long have you use it?

I've had about 3 years
What thing do you like most and least?

What I love most, very good sound quality, the ability to connect up to 9 + 1 Subwoofer speakers (7.1 + 2 other FRONT speakers on another channel).
What I like least, its too poor equalizer (bass and trebles only), and the fact that it is not compatible with DTS HD (no HDMI).
Have you tried many other models before buying it?

I have owned a Yamaha lower class before, well I do not regret having changed, Denon still follow me long I think.
How would you rate the quality / price?

Very good value for money, having paid about € 350 on its video.con-at the time, while he was selling up to € 500 in stores.
With experience, you do again this choice? ... *dropoff Window

I would look at other models anyway because it is changing all the time this type of material, and also audio standards (such as DTS HD ...)
