I have a question for those that have moved up from a single receiver to a receiver and amp combo or a pre/pro combo; "Did your sound quality improve immensely?" I currently have an Outlaw 1050. It does quite well with my more modest Klipsch speakers and SVS subs. But I was wondering if I might hear a difference if I moved up to a separate amp controlled by my Outlaw? Is the sound quality alone justification enough to purchase one? I know in car audio when adding a powerul, well made amp to your head unit there is a night and day difference in the quality, presence and punch of the music. Is this the same for home theater?
