Hudsonhawk, not trying to derail anything; it's just that to my ears the McCormack amps present the opposite of a "tube like warmth".
The McCormacks have a tight extended rhythmic bass with an extended high end, not a tube like warmth which would indicate a soft bloomy bass and rolled off treble. The only things the McCormacks have in common with tube amps is a forward presentation and liquidity in the treble.
