David, read your post, sounds like me! I have a denon not too old has 100Watts per channel. And I am pushing definitive speakers. I have the 7001 towers, they did not have the 7000 others wise that would be in the room right now. I just ordered the SR875 Monday and they should be here any day now,(crutchfield). I down loaded the manual so I can get things going when it arrives. One thing I read is the ability to bi Amp the towers using the surr back speakers. Can't wait to try that option out. Now this is if you are not using your surr back, I am using only surr speakers for a 5.0 setup. I was wondering about the definitive cube speaker you mentioned, is that a sub woofer, because you already have 1800 watts in your towers, thought a sub woofer would be an over based set-up?? Oh I am paying $1400 for Onkyo, 2K less then when it first came out. I also ordered a Sit on top two fan cooler for it from Studio Tech, and there U-60 componet cabinet, Should keep thinks cool! I am 70% Audio, and 30% Vidio, so I really enjoy listening to music when I have the option and free time!
