Naresh,
Since you have put music as priority, you might want to check out CA and Marantz as well. These are more musical than denon, although denon is a better alrounder imo.
Another point to check would be to get an AVR with Pre-outs. This will help you easily integrate a 2 channel dedicated stereo amp - should you want to set up a hifi in the future and share the main speakers.
Most of my friends who had set up expensive HTs more or less use it mainly for music only. An occasional movie during the weekend is not ruled out but watching movies is proving to be a very time consuming for most thanks to the hectic schedules or the weekend chores
Happy auditioning!
