depends what sound profile you are looking for and what speakers you are driving
the cj prem 11a is a nice relaxed tubey sounding amp but has trouble with controlling and driving harder to drive speakers... best to use higher efficiency speakers with benign impedance
i personally think an older cj preamp/linestage into a prem 11a is too much of a good thing in the warm and fuzzy golden glowy sound direction, but as i said, it depends what rest of system is
