As as someone new to tubes, you made an excellent choice. I'm on my 4th c-j piece (Prem. 16LS II) and have found their stuff is reliable, well engineered, and made by a company with superb customer back-up.
My experience with Tab Sigs is that they can tend toward the bright and lean. I think it'd be worth trying the triode version (you'd still be push-pull in operation) which most likely would be cleaner but more natural in sound. I had a Mesa Barron which was switchable and found triode to be the most musical with my ProAc 2.5s. I now use SETs but did borrow a c-j 60 (triode version) about 1 1/2 yrs ago out of couriosity. It was wonderfully musical and if I ever leave SET land (fat chance) I'll buy one of them or whatever c-j has current.
