Do you understand Japanese?
Playing with the 2910.
The manual was obviously translated from another language by someone who is not totally fluent in English, and is sometimes difficult to understand. Hooked the 2910 multi-channel outputs to the external decoder inputs on the Yamaha receiver. I have a pair of DCM QEDs from the late 70s for the surrounds. My room is small, so I have the DCMs in a line with my listening spot along the back wall. Not an ideal situation, but, for now, it's what I have. Santana's "Shaman", DVD A creates a panoramic sound in a 180 degree arc.
DTS and Dolby Digital movie soundtracks sound great, too. I have an old WEGA Sony 27 inch, and I tweaked the picture using a THX test disc on the Tombstone DVD. The 2910 picture and color adjustments are complicated, it seems to me, and I'll have to study them more to understand how to use them properly.
Paid $630US for the player at my local audio/video store and plan to use it for both audio and video. I thought it was a good compromise between a totally outrageously expensive unit and a cheap unit. Still expensive, for me anyway. I rationalized the expense in several different ways and when I kick back, close my eyes and let the music engulf me, I don't even need to rationalize. It sounds good enough to justify the expense.
