I'd also suggest looking at Hegel based solely on the fact that the previous owner of my T+A PA 3100 HV settled on the Hegel 590 because he wanted to move to a one-box solution. He thought Hegel competed well against the T+A sonically, which is no mean feat as the T+A is truly extraordinary.
I know it's just one (two?) persons opinions, but that, along with the fact that Harbeth powers their speakers at shows with Hegel, I think speaks volumes for the brand.
