I heard a Crown Macro Reference (as I vaguely recall) at an air show: the sound was incredibly loud out on the airfield, and standing about 100 yards away from the speakers; but if you're looking for detail, precision, and accuracy, you might consider alternatives to pro. audio. Not sure what speaker load you're driving, but I read a review that the Crown Macro Reference -- "which should have been able to drive just about anything in the universe" -- choked at the load that Sound Lab A-1's presented; yet, a pair of 225 watt monoblocks did an impeccable job comparatively.
The Crown XTI 2000 puts out an amazing 2000 watts @ 2 ohms, but then again can it and will it in fact drive the suffocating loads of an electrostat setup -- if this is what you have -- or will the overload lights go bonkers as apparently occurred with the Macro Reference's attempt at driving the A-1's. Although Crown is a world-reknown Company with a dominant presence in arena type settings, it would be interesting to see and feel a crowd's reaction to relatively more precise amplification by Threshold, Krell, Levinson, VTL, Classe, MBL, etc. If these manufacturers can build machines that drive two ohms or less, I wonder how these machines would fare driving much less exhausting eight ohm pro speakers. I'm a relative novice at this stuff, hence the many wonders.
