A balanced sound... basically a good representation of the music or movie I'm listening to. My older polk satellites were a little bassy compared to some Acoustic Research and Bose at the time which I would describe as "bright" in terms of too much midrange and highs. Listened to some Paradigms and Klipsch floorstanders the other day and the Klipsch sounded more balanced than the Paradigms. Also listened to some Polk Monitor 50's 60's and 70's. The 60's sounded pretty good but the 70's were too bright - they really altered a male tenor voice almost making it sound like an alto. The 50's were too flat... not enough bass. I know sound is subjective... I hope that helps.
