I had the A3s with Primaluna dialogue HP monoblocks running KT120s (150 w/ ch). It sounded slow and boring. I later tried a Luxman L509x and the speakers came alive. Technically, at 4 ohms the Luxman has a bit more power (70 w/ch more if I remember correctly) but I don’t think that was at issue. I just don’t think there was any synergy there. I think for those sealed speakers an amp with a higher damping factor may be a better match, but that’s just a guess on my part.
