i had cat reference once in my system. It is not as good as the signature. There is a big difference between the Reference and even Signature MK I. reference is a bit bass shy. In fact, I talked on the phone with Ken Stevens (CAT), who confirmed it. He did not recommend bying a Reference. My (as well as his) suggestion would be to find any CAT Signature; MK I, II, III, or the Ultimate, which is in the top 3 preamps at any price.
