I'm assuming that you "heard" something thru those amps you picked? Start there and keep a budget in mind if needed. This is the altimate question because more than anything else; there are practically enough speaker manufacturers for every pair of ears
My rule of thumb though would be to purchase from a manufacturer that specializes in speakers. Gear companies make attempts at it but, they can't be great at everything. I have been very happy with Paradigm speakers.
This is the fun part,
