Summary: This Denon is worthless. Can't even use it for my home theater now. Plugged this receiver in after firmware upgrade and it has a delay in the voice on screen. Thought well that is no problem I will use the delay fix on the unit. Well it is delayed in the other direction.
Summary: I have been really really disappointed by my purchase. I bought a Denon AVR 3311CI two and a half yrs ago.. it seemed a great thing. It had tons of features and I loved the networking aspect. After I found the app for it, it was even better. However even from the beginning it had problems.
Summary: I purchased this unit toward the end of 2010 and got about 6 months out of it till the network card died. Same issue as is mentioned in several reviews here on Amazon and on AVSForums - an IP address can't be set nor obtained via DHCP and all network features are locked out.
Summary: Worked great for 6 months, then picture started to flash on and off whenever watching a DVD. Tried everything on my end to try to diagnose and fix the problem: tried switching inputs and outputs, new cables, total system reset. No help. Drove an hour to the repair center.
Summary: This unit is loaded with features at the price point. The only problem is a tendency to have the main board fail. The part, called an HDMI module is the main printed circuit board. I have had mine for 7 months and just got it back after replacing the second HDMI module.
Summary: About 2+ years ago I spent over $700 on a Denon S-52. All of a sudden, it stopped working. So, I sent it in for repair. It was sent back to me unrepaired with no note and no call. But, between shipping and repair service, of which there was none, it cost me another $150.
Summary: I slowly stop to work feature die one after another I serviced this junk twice in first 2 years each time replaced motherboard covered by denon. Now after warranty at first I get noise during up-scaling. Can't upscale. Now most of the DSP slowly stop to work.
Summary: Ordered unit online and some Klipsch. Connected sounded awesome. Set up access tot the PC to play my music great. Network radio stations no problem. The sound was so clean it put a smile on my face. After a month or 2, the Network went out partially.
Summary: I will not suggest this AVR. It has a known networking issue. I Bought this unit more then 1 year ago and now I can not play iPod, pondara, internet radio. The customer service is not very help full either. They are aware of this issue. One more problem is this product heats up very fast.
