I had some Klipsch Heresies. They weren't my favorite. Lacked bass....and, well, I think the horns are really an acquired taste....they kinda put the treble right in your face.
If you're looking for Vintage speakers, I love the 1980's Infinity speakers- RS Kappa Series (8 or 9's....and don't let them scare you the whole "amp killer" thing.... Carver amps can handle them. I'm partial to the original line, not the x.1 's). Or their predecessors, the RS series, RS III, RS II, or even RS I if you have a lot of $ and space. I have a pair of RS IIIb's that I swear are the best ever.
If you're looking to buy new, I'm partial to Bowers and Wilkins. I don't own any, but every pair I've ever heard is fantastic.
