Dave,
I'm currently running a pair of the original Micro Utopias using a KR Audio tube amp. I was originally under the impression that my amp was putting out 18 watts per side, now I'm beginning to find out that it might be only 12, either way these are very easy speakers to drive so I definitely recommend tubes. I don't know your exact price range, but there are lots of good models out there from KR, Cary, BAT, VAC, and others. Remember also that you really don't need a lot of watts. Audition, have fun, and remember the searching can be as fun and important as finding the right amp. Good luck!
