Summary: Denon has MAJOR problems with product quality. These units have long-standing problems with the network cards and have done NOTHING to fix the problems. I have yet to get any response for connection issues in 5 years.
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 purchased my 3311CI June 9th 2011 and figured I'd give an update since it's been right over 2 years and 2000+ hours of use since I've had it. I didn't know about the network issues until AFTER I purchased it and started reading about some of the problems people were having on the AVS Forum.
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: 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 bought the first 3311 from Crutchfield, it went out in less than a month. Crutchfield sent another one. It lasted about 6 months, sent in for repair. Recieved unit about a month later, it went out in about 8 months. I placed it o a shelf and bought an Onkyo, NO ISSUES.
Super great sound & plays well with all generations of Apple iPods & iPhones

Summary: All in all it's a great receiver. The music is astounding when it is paired with definitive speakers. I don't use the network card so I can't comment about that. If you're looking for a great receiver and the network feature isn't on the top of your list, then save a lot of money & get this unit...
