The tube compliment is the same as a VT100mkIII with eight 6550C power tubes and four 6H30's, so the heat is exactly the same.
The power is spec'd at 120 watts per channel which is a tad higher than the VT100 series amps, but the supply has a little less energy storage. Subjectively this amp has a better grip than the VT100 mkI, II, or III. I can't comment on the Maggies with this amp specifically, but ARC amps tend to do very well with them.
I'll let someone else comment on the excellent sound because I am a biased ARC dealer.
