MG 20.1 or Wisdom audio m-75

I'm taking all this in. Would like to hear from some folks who have owned and lived with the wisdoms,they are a complex system with the crossover and all the possible settings. Harry Pearson had these for a time as his reference and in the 2000 reveiw of the M-75's he used a Krell fpb 600 on the sub's and different amps in his tests of the planar towers. It was not my understanding that running the system with dissimilar solid state amps was a problem due to the fact that the crossover could make adjustments to equal thing's out. For that matter, I have heard many enjoy solid state and tube combo's on maggies with beautiful results ? Whats up with that ?

FEDREAMS, Thanks for your reply. What amps do you have powering the M-50's,and what other speakers did you audition before buying the Wisdom's? what's your room size?and what do you think you will be gaining by upgrading to the M-75's ? SHAMAN
