I know this is not exactly what you are looking for, but I have McIntosh MC 611’s driving B&W 802D’3. One step down from you. I previously had a Classe 2300, which is a very good stereo amp. I found the McIntosh to sound slightly on the warmer side, but very dynamic, clear, and detailed, Bass and mid range are fantastic. Highs are dynamic but not bright or harsh. I know many say McIntosh is soft and romantic, but I would not describe the 611 that way. I think maybe the newer models are voiced differently from prior models.
