Let's face, it, for $10K used, you have a lot of excellent choices for rock/jazz. Optimizing with your amp and your personal preferences for sound and style should be the determining factors.
I say the OHMs mainly because their unique design allows them to transcend what most speakers are capable of doing at their price points, which are based on room size, not relative sound quality. If you take to them, you will probably never look back at more conventional designs again. If your room is not too big in particular, you can get optimal results for a very modest price and spend teh rest elsewhere if you like. So the potential up side is considerable.....
