Rrog, I promised that I was not going to add anything else to this thread . . . but your comment set me off, not in a bad way but a good way. I looked over the thread yesterday and saw, as usual, everybody chiming in with their favorite amps. To me, it's like asking what is the best speaker . . . and there is a thread running asking that very question with over 1300 hits. My point, if it's not clear already, is that there is a lot of fine equipment out there. I happened to wind up with Audio Research, but that's me. I freely acknowledge that many other makes are just as good or better. I also want to reiterate what I said about system synergy. Some amps will will work better than others when driving a particular speaker, e.g., electrostats, horns, dynamic cones with unusual impedance curves and phase angles, and so forth. That's why, IMHO, I don't make equipment recommendations. Of course, if someone makes an unfair comment about a particular piece of equipment that I familiar with, I will respond, as I did above.
FWIW.
