I have two Musician III, Mk2 with Bybee upgrades (not monoblock but each stereo on AA Beethovens) with Cary SLP-05. The Cary is not using original tubes--now Raytheon and Mullard rectifier. The sound has excellent dynamics, detail, and decay but is neither fatiguing nor lush--very enjoyable for my tastes.
Good hunting,
Will
