Summary: I purchased this amp in July of 2010. I didn't have the money for speakers so i hooked it up and was using it as a passthrough. i finally ordered a set of Definitive Technologies speakers, which by the way are fantastic.
Denon Quality Is Poor. Two Denon AVR-3310CI receivers failed.

Summary: This review is for the AVR-3310CI and probably the AVR-3311CI (per other reviews). I usually do not write reviews. However, after buying two of these AVR-3310CI receivers at different times (6/2010 & 11/2010) and having both fail I feel impelled to give my story. The first one failed twice so far.
Manufacturer Technician States DONT DO FIRMWARE UPDATES That create Problems!!!

Summary: I really liked all the features of the 3310ci model. It recently was priced in the Mid $500 range...What a deal!!!...After reading all the reviews and Negative comments regarding Malfunctions while attempting to do Firmware Updates....I decided to contact Denon USA.
Summary: The Denon brand has long been synonymous with high end products and premium prices to match. This was my second Denon thousand dollar plus receiver and I suppose I only have myself to blame for making the same mistake twice. Sound quality is premium. But I will limit my comments to usability.
Summary: Stay away from this unit! Problems began within 1st few weeks.It will be working fine, then it will jus quit & a pulsing sound will come from the speakers. it will only play again if i turn the unit off then back on again. I shipped it to Denon repair twice & problem still exists.
Only pure direct mode works fine...defective dsp simulation

Summary: 2nd Update...I'm getting closer to what really goes wrong. I have a HDMI out from 3310ci to a sharp LED TV. When I turned on the TV, or unplugged this HDMI cable, the receiver immediately went back to normal, problem gone.
