I dont know Glen or Bill, but 10 minutes with either of these guys might result in a goldmine of information or it may result in ten minutes of competitive product bashing and only an attempt to sell you their products. I hope it is the former, but please be careful.
I do know that in my conversations with John at DeVore he often shows with push pull designs which may or may not be entirely the result of sonics. With our group it seemed that we didnt know how much better the system could sound until we added more power and what I believe to be an inherently superior amplifier design (provided the speakers present a higher and stable impedance load).
Seek advice first from those that have no dog in the fight.
