Cool system, Pubul57!
I am, myself, a CAT pre owner - SL1 Sig. Mk 3. I really like this preamp a lot! Each time I listen, it's sound pleases me a lot. Ken S. informs me that the Ultimate Mk2 is head & shoulders better. One day I'll upgrade to that.
Also, someday I'll join all of you in the JL2 club. It's on my radar!
