I'm surprised so few of the responses have suggested actually auditioning some speakers instead of talking about them.

yozhek, you should search out every mid to high end dealer within a reasonable distance and actually audition some speakers. Otherwise, all you've got are recommendations of someone's favorite brand or particular speaker. What I like you may not and vice versa.

Buying speakers on a recommendation without auditioning them first is like letting someone else choose your mail order bride. The chances are slim to none that you'll like what you get.
