I recently purchased an Audio by Van Alstine VISION SET 400 AMPLIFIER for two grand that sounds better than the two solid-state Mac's I've owned previously. Two thousand dollars is a fraction of the cost of these Mac's. Yes, it's a utilitarian black box, no meters and doesn't need a hand truck to bring into your sound room, but it sounds more like music to my ears for a fraction of the price.
Now, on the other side, I have a MAC MC-275 IV that is magical in the way tube amps can be. I wouldn't part with it unless I was being held hostage at gunpoint, and to be honest I might not let it go and take the bullet. Now of course that's blatant bullshit, however I might die for Angie Harman, but I digress. It gets to the point of how good a MAC 275 sounds but not their solid state for lots of money.
