Subhash's advise is good, though I dont know about the night and day that he mentioned!
Since you haven't mentioned your budget for your gear in this thread,do be prepared to spend a bit more for the separates compared to a AV receiver.
I was seriously considering a Denon or Onkyo while in the US a few weeks ago. Since I already have separates( as well as integrateds) for 2 channel audio, I know the difference, and a couple of nudges from Subhash and Santhosh did the trick-I ended up buying a used Emotiva LMC1( which I can upgrade should I need to at any future date), as well as the Hypex UcD 180 modules to build my own 5 channel power amp. I wont be upgrading this-I consider this a keeper.Output is 100 wpc @ 8 ohms which is more than adequate for my HT room.
The cost?
About thrice that of the 3 week old Denon 1910 that I was on the verge of buying off craigslist New York.
