I have had problem after problem with Denon. I have about $3,000 in speakers which were used for about 8 months (purchased everything brand new), I took my Denon AVR-1910 receiver into a "Certified Denon Dealer" which everything they had in there shop was extremely old and the computers they were using to test the receivers were ones that I used when I was in elementary, the old Apple computers. After taking my receiver into there shop 4 different times they had a new excuse every time for what was wrong with the unit or how "it was my fault" it wasn't working, when I knew for a fact that I had everything setup correctly.
So I got fed up with them and sent the receiver off to Denon, which was in pristine condition, not a single scratch on the entire unit! Three and a half weeks later they sent me back the unit with the receipt saying that they replaced an HDMI Board and tested everything and it worked like it should again. So I unpackaged the receiver and noticed some scratches on the back which I didn't think it was to big of a deal, then I started looking at the face of the unit and the knobs have lots of wear on them, one being really scratched up, and then I noticed scratches on the top of the face, and some even on the glass display peice, and to top it off there was a dent on the right side of the unit! I called up Denon and sat on the phone for 20 minutes, finally getting a hold of them, they told me it was the unit that I sent into them. Luckily I got pictures of the unit before I sent it off, so I can e-mail them pictures of before and after. I won't be surprised if they "didn't get my e-mail".
In my opinion, I wouldn't recommend ANYONE to buy Denon, I know that after this extremely disappointing exhausting waste of time for over 6 months now of problem after problem with Denon, I am fed up with them and gave them plenty of times to make things right and they just can't get things right.
