I have demoed the Onkyo Integra 7.3, Rotel RSX 1055 and Rotel RSX 1065. All were outstanding. Yes they have only power for 5 speakers but all have pre-outs for adding extra power amps for a 6.1 or 7.1. You can go all pre-outs and setup all separates if you want. Rotel has an edge where-in when they say that their power rating is 75W or 100W they are truly 75W or 100W on 5 speakers. The Onkyo had more features but when Sound & Vision Mag did tests the 100W ran about 78W on all speakers driven. Music quality on Rotels are always clean clear and powerful. I would recommend them. I have the Rotel RSX 1065. It runs only warm after 5 hours of music and 2 movies back to back. THe only issue I have with Rotels are they are damn heavy. So move it to one spot and never move it again.
The Elite series as commented by some high end shops only good with the lines of DVD players and TV Plasmas.
