I am somewhat in the same market. My current pre/pro is a Rotel RSP-1066, which is quite nice in its price range. But, now that the rest of my system is shaping up nicely (Thiel speakers and Theta amps), it has become one of my weak links. My top contenders are the Krell HTS 7.1 or the Theta pres (Casa Nova or CasablancaIII), although Sim Moon Audio, and EAD are probably also on my short list. I would consider Classe' and Bryston as well. However, my thoughts are that if I go for a no holds barred, final word pre/pro, I am really looking at the HTS 7.l or the CasablancaIII. But, if I want to focus on getting awesome 2-channel (which I do), and I can live with 5.1 (which I definitely can) and no multi-channel input (which I am not sure if I can live without), you can pick up a great deal on a Casa Nova right now.
