I think Triangle Antal 202 or even Celius (a tad over your price) might be your ticket. Easy to drive (92 db) and one of the best values you might find if you are looking for detail, amazing midrange and speed. They have full bass and sound full range on most music.. but not the lowest organ notes-they suposedly only go down to 45/50 Hz. The only criticism on these speakers has been bright treble, (more associated with the version before the 202-which has new tweeters), but with the associated gear you have, that would not be a problem.
Good luck.
