I have heard plenty good about the Yamaha 863 and Denon 2310... planning to get an audition soon for them. I am also intrigued by the Sony 2400ES ... supposed to be very good for movies and music and upscales to 1080p! unfortunately can't audition in India 
I can get the Yamaha 863 for approx INR 48K, the Denon 2310 for approx INR 46K and the Sony 2400 for about INR 41K... Budget is not a big concern. I am hoping to sell off my existing Onkyo 705 for between 25K and 30K and so I am well covered there.
I want an AVR that does movies and music well and which I can bi-amp. My 705 was good for movies and so so for music... till I bi-amped it. That changed its personality and made me a bi-amp convert!
While the audition should help me with deciding between Yamaha and Denon... the Sony seems like a very good VFM deal... but I have no way of knowing first hand... so I though I would take your help...
Any suggestions? Are the yamaha and denon better than the sony that I shouldn't spend much though over it?
