I heard the DVD set to stereo and put in the remastered Rush album "Presto." It is a very flat neutral recording. It is HARD to make it sound great. Let me explain my setup a little. The total max wattage for the LSi15's are 250 watts. They are 4 ohm speakers. I am one who believes that more wattage need not equal volume as much as it equals authority and clarity. Mainly clarity. The ability for a driver to push out and in much better. That said, the 7500 powers ONLY the fronts and center. the 2200 monos power the surrounds. I am using two channels each on the 7500 to bi-amp the fronts. In all, I am throwing 600 watts per speaker!!!! Though some say the center does the most work, because it lacks an 8" woofer and its crossover is set to 60 hz, I think 300 watts plenty considering its published max wattage is 200 watts.

So, what does it sound like? Even at low volume you can hear the power and authority. It was nearly 9 pm when I was done with the firmware upgrade (only one restart) when I got everything set up. I am using Outlaws audiophile grade PCA cables (7 of them). I stereo mode, "Presto" sounds like I am there. There. Heat does not seem to be a problem with the 7500, but just in case I have a brushless 120mm fan ready. Actually, the 2200's run hotter. I am freaked that I actually own this gear! Freaked!
