I'd love to see the results of a multi-sample blind A/B/C "Mac challenge" taste test, with A being a Mac 250 or 2300 or whatever does "it", B: another quality solid state amp like a QSC or Crest or whatever, and C: the Twin output section inline, or perhaps a tube power amp like a 50/50. The gear would be behind a screen as you noodle away, and an assistant changes out each power amp without you knowing what it is. Better yet, I'd love to allay my own skepticism in the only way possible, by getting to A/B a Mac vs my Ashly, which I have no complaints about.
