Best JBL's you have heard

I have a pair of highly regarded speakers that sell in the $4,000 price range. Several months ago I purchased a pair of JBL L200B's off Audiogon. I am amazed at the sound quality of the JBL's. Comparing both speakers back and forth, the 200's more than hold their own. I have two questions: first, is it just me or have any of you had similiar experiences with vintage speakers, and second, what are the best JBL speakers you have heard?
