I never liked CJ tube preamps but I've never tried a "Premier" model. The old CJ PF-R is an incredible sounding solid-state model.
In the $3000 to $4000 range, I would seriously consider the BAT VK30SE or the VK50SE. Unlike CJ gear, BAT includes balanced XLR in addition to RCA in/outs and their user interface is superb. I'm running a BAT VK30se into two CJ power amps. Of course I'm not taking advantage of the balanced outputs from the VK30se but that may change when I try some other amps.
