Jim, In defense of Tvad, although he has his own voice and can speak for himself, this thread is getting a bit long. Now I'll make it a bit longer rather than hear you guys wrangle.
In my opinion Tvad has exacting expectations (don't we all!) and the level of bass resolution with tube amps, at least the ones he tried, were not up to his level of expectations. Thats all.
None of us have definitive opinions about anything. Faced with the alternatives between the III's and the Bolero's I picked the Bolero's because they did what I wanted speakers to do using tubes. I doubt that either of you would be happy with them no matter how they were driven because we have very different expectations. If I had been confident that the III's might have sounded good (to me) with tubes I might have given them more consideration. But I guessed they wouldn't and I just didn't want to have to use SS amps, even Pass's (or according to my preferences, some of his old Threshold SA series amps).
I think what the OP should draw from this is that the III's are like a fine instrument, their sound is greatly affected by the choice of amps, and while they may be a much better speaker than the I's or II's he will have to be committed to finding the right amps to drive them, and hls Mac may or may not be the right amp for him. If he is not prepared to change it out he should either learn to be happy with what he has (my first choice, because he already is happy) or pick a speaker which may not be so critical of its source.
FWIW.
