@kijanki In the Paul Seydor review you posted, I think he was using subtlety to mock audiophiles and not denegrate the AHB2. He essentially was suggesting that audiophiles at least sometimes seem to be more interested in playing around with gear and swapping things out and they wouldn’t be interested in the AHB2 which produces clean minimalist distortion sonic accuracy which audiophiles SHOULD want. He was being sarcastic.
I own a pair of AHB2 and use them as monoblocks with my Magico A3s and REL T/9i subs. They perform well and as advertised. But this is in the context of my system and room. So others experience may be different.
