$1,000 - What amp?

I have been looking at them all. The McCormack DNA 125, MF A3cr, Aragon, Krell 300iL, PS Audio HCA-2, and some others. I am just not sure what to buy with a grand. I have a Jolida hybrid right now, and I like it a lot, but it doesn't have enough power and is too sloppy in the bass.

I do want something that is musical, and detailed with tight bass, and lots of gas. I have Michael Green Chameleons which aren't that hard to drive.

Thx for any ideas!
