Richard,
I have MG-12's with modified crossovers. I am indeed driving them with an HCA-2. I sold my CJ MV 52 prior to buying the maggies so my comparisons of push-pull v. digital where on meadowlard kestral hotrods(which are known to be tube friendly). Still I preferred the clarity of the PS over the CJ in the bass and surprisingly in the treble. Again, it was not the etched treble I was used to hearing with other SS I had heard. It was not about power or slam, I preferred it musically. My other reasons are stated above, it's an easier amp to have around the house and in my current set-up, I just don't need the heat, size, and expense of an tube amp suitable to drive the maggies. Search the planar aslyum archives at Audioaslyum and you may get some more info.
good luck,
Pete
