Are you talking about Harmon/Kardon branded speakers or speaker manufacturers associated with Harmon International?
Harmon International owns JBL, Infinity, Revel, and SoundCraft. I'm sure the super high priced JBL's sound ok. I know that the super high priced Infinity sounds pretty good. The Revel is great but I have not heard their latest offerings. All-in-all I think that the speakers from Harmon are good but perhaps over priced for what they are.
THe Lexicon and Levinson stuff is very good.
