Don't know why my two previous attempts to post to this thread didn't make it, but I'll try again.
Audfile74: A pair of Sound Lab U-2s (similar in size to M-3s) I sold were driven by an Innersound ESL-300 amp, which is capable of driving the speakers to fairly loud levels, though you may prefer other amplifiers, including some mentioned in this thread. The speakers readily reveal the character of everything else in the chain, especially amps that are bright, too laid back or polite, and so on. If the sound is either fatiguing or uninvolving, keep looking.
Rwwear: Interesting story. The Fouriers could be spooky good but were finicky. I owned one of their stereo amps at one time.
