Sorry I can't give any advice specific to your amp/pre combination. But I have had great results rolling NOS tubes in my Cary SLI-80F1. Specifically Sylvania 6sn7wgta's and amperex 7308's with genelex kt88 reissues.

I did try NOS 6922's in my cj premier 16 and did not hear any significatant improvement.

My experience with changing small tubes in my amp (not a c-j, but a VAC PA 35.35), was not a small improvement. I changed the EH 12AU7's and 12AT7's for NOS Telefunken 12AU7's and 12AT7's. For me, a very worthwhile improvement.

Thanks for the responses. Thinking of some nos tung sols 6sn7gtb's. Going to place the order very soon! The sovteks are looking/sounding a little tired.

Just put in a new set of Genelex Gold Lion 12ax7s from Tube Depot in my CAV50 to replace the NOS Telefunken smooth plates and these made a huge improvement in detail and dynamic range with tighter bass. Very quiet too and the noise floor dropped considerably. Recommended!
