@xyzsantabarbara, As I understand it; yes. I believe many of the Krell’s do, that the Mark Levinson ML 2’s did, some of the Pass Labs might (limited to 4 Ohms maybe?)? I wouldn’t swear on it though. I’ll hazard a guess that the Class A output is halved as the output doubles as impedance is halved. Though most times one cruises along at low power output, that output increases rather dramatically exponentially. You’ll have to decide how relevant the Class A output in your circumstances. Keep in mind that available higher total output can potentially protect drivers from under powered clipping damage, and the ear tends to be less sensitive to the cross-over distortions of Class AB at higher volume levels.
These are the areas that separates typically have advantages over their integrated brethren; the ability to double down and and the ability to stay in Class A output longer when doing so.
