Best rock/jazz speaker under $10k used


What speaker under $10k used can rock hard but also bring out the best in jazz voice? I love the sound of planars for voice, but I sometimes I really want to shake the walls and bring out the best in a power chord. Opinions?

Sophia 2 are pretty cheap used. They have good vocals and strong bass. The drivers lack ultimate integration and resolution. But at their current used prices they are a very good deal. The big dynamics will be good for rock music.
When I read the title, the first speaker that came to mind was the Prelude, even before opening the thread.
I would second the Prelude.
Thanks for all of your suggestions so far. I now know of speakers that I hadn't before. Keep them coming!
Check out the JTR Triple 12HT's. They can handle up to 1600 watts. They are Pro speakers, redesigned for the home. You can read about them over at AVS.
