This was our original 5.1 set up:
Receiver Onkyo TX-DS797
Front Speakers: Bose Acoustimas 5 Series II
Center: Bose VCS-10
Surrounds: Advent Bookshelf
Sub: Velodyne CHT-10
With this setup we enjoyed playing music, TV and loud DVD movies, watching on our Pani TH50PZ700U. We bought a Sony BDP-S300 Blu-ray player which was attached to our Pani via HDMI connection. Although the picture quality was stunning, we wondered what we were missing sound wise with Blu-ray movies.
Then came the decision to go with a Denon AVR 2310 because of the good reviews on the AVS forum and the 5 HDMI inputs. We set up the Denon temporally on a TV tray (no heat problems) and after connecting the speakers, ran the Audyssey setup. Audyssey complained that the right front speaker was out of phase and then completed and stored the settings.
We have been have been very disappointed by continuos shutdowns (via the protection circuits of the receiver) when playing Blu-ray DVDs such as "Pearl Harbor" or "U571". This occurs with any explosion or other loud sound when the level is around -25dB. The movies play ok at -30dB, but at this level, the dialog is often hard to make out.
With music, TV, or CDs we get great sound and can easily get the level very loud (down to -8dB or so), but with DVD movies, the 2310 starts shutting down with the power indicator flashing rapidly several times a second., once the level gets to the mid -20s. It seems that volume-wise, our Pani's TV speakers can play movies louder than the 2310.
I called Denon with this problem and they suggested that there may be impedance or crossover problems with the Bose Acoustimas speakers. He said that Denon and Bose don't play well together. So we went to Bestbuy and had them play "U571" using their display receiver, a Denon AVR 2309CI, through a pair of Klipsch WB-14 speakers. I turned the level down to -10db and the sound was very loud and very clear. None of the explosions shut down their 2309. So we bought the WB-14s and replaced the Bose Acoustimas speakers. I re-ran Audyssey and stored the new settings but my 2310 went into "protection mode" and shut down when the volume got lower than -25db, playing "Pearl Harbor".
I would appreciate any thoughts or suggestions. Do you think I have a defective 2310?
