Sashua,
Perhaps you should also consider two Spectron Musician III MK II in mono-block configuration. These amps in balanced mode have all the qualities you're looking for plus a lot more. There is more control, more finesse with a total absence of grain anywhere in the audio spectrum. There is that effortless sound while at the same time staying composed that only the best of the best can achieve.
IMHO, the Spectron amps don't sound like a typical digital amp, they just sound like great amps.
