Regardlees price, do you think that the Classe CAV-180 is too much for KEF home THX speakers (TDM 23C-23F & 34DS Dipoles), I have installed in my dedicated room? Or maybe the Bryston 9B SST THX is a more logical solution? I also have in mind the Primare 30.5 . I know that the Primare is at another category regarding price and quality. Regardless price which is the more suitable power amplifier ? Note that the dedicated room is soundproofed and the whole construction is like "box-in a box".
