I had an ATC power amp the P1 to drive my harbeth (similar spec to atc) and they are unsung heroes..... The sia 150 mentioned would suit really well. And don't go on first few song impressions as this combo is good for hours of sweet listening.
I sold all my gear when I went to big tannoys with 96db and bought a luxman A class with 20w.... Very different sound. But wish I'd keps that ATC as backup
