Nice to know I'm in good company. grin What's remarkable about the Mac amps is how they sound so similar whether solid state or tube design. I've always suspected its because of the autotransformers that they use in all their amps. Nevertheless all the Mac amps have nuances to their sound. Since I made that post I traded in some gear for a pair of solid state MC501 monoblock amps for a tighter bass sound, though they lack some of that air and mid range emphasis that you get from tube amps.
