Thanks, haha! Yes there are some heavy bastards among them... my first one-walk-from-car-to-stage gig with the KPA is an experience I'll never forget. I am keeping the cabs however, specially a 1x12 Two-Rock, 2x12 Two-Rock and 2x12 Marshall.
I must add though that 95% of the time I play my own profiles of these amps. I have a recording studio so I have made quite some profiles of each of these amps with quality mics and preamps.
If you are happy with your own profiles, sell all of your amps, buy new amps you would like.. profile'em all.. play .. repeat.
