Well, crisp and detailed are often euphemisms for bright. I don't do bright much. I prefer smooth and warm.

JL Audio "slash" amps are good, as are DLS, Genesis, Brax, and Zapco.

For what you're describing you might like Focal or Rainbow. I think you would like Dynaudio or Morel or DLS (because I think everyone would with exposure), but they're not bright. I know Dynaudio can it and sound amazing.

I am not a big fan of Diamond Audio.

Budget does play a role, along with what fits. Are you having this professionally installed, I presume? And are you doing the rear doors?

I would say that a DLS UP6 set in the front, a set of M6 in the rear, and the MW110, powered by a CA41 and a CA21 should work very well and be installable in that budget.
