Ahhhhhhh! SoundsGreat, we finally agree on something!! I am sure we can start a great relationship on this note.
Baburaj, a couple of points to look at.
1. The Yamaha 461 seems to be an old model and that is the reason they are not supporting HDMI. They have a new model called 463 that has similar specs but supports HDMI.
2. The Denon does sound good. I am sure if you liked the sound of Yamaha you will like the sound of a Denon unless you prefer sound to come and hit you on your face. As I said before, the Denon will sound softer and warmer.
3. You should also look at Onkyo's 506, a new model that they have introduced. Onkyo, for the last one year, has been beating both Denon and Yamaha on technology and sales. Their 600, 700, and 800 series were runaway bestsellers last year. I have a Onkyo 875 that I purchased for their Reon upscaling, and I am very happy with it's performance. Actually both Onkyo and Yamaha may sound similar to the ear.
I am not sure about Yamaha's dealership in Bangalore. You can contact their Mumbai office number (022-2640 7318) and get the details. If you are really interested, I can check with their dealer in Chennai, get the price, and see if they will ship it to you in Bangalore. This is a company called Torvin and their contact detail is 044-2858 7256.
If you need any other help, please let me know.
