Well, with the Rush CD's I have the benefit of being able to compare them to lesser systems and perfect or not I can tell you there is great improvement. I have a relative who is very well to do. But he likes Klipsch. He also likes the high end power horses like Makintosh (sp?). He would make me listen to Rush to hear (oddly enough) errors in the recording process. Now I can hear that too!!! I was listening to Rush tonight with my wife. It sounded loud and clear in the basement. I assumed it was loud upstairs. It was not. simply put, it is so tight in the listening area that is "sounds" loud but it is quite controlled. I wish I was Hercules because I would take my 7500 and put it in bed with me!!! It is pretty obvious that the power it provides is serious. Between you and I it sits on its own 20 amp circuit. I am thinking maybe I should have gotten the 7700, but I don't mind using the 2200 monos. really, Outlaw makes quite fine products!
