Tube Rolling 12AX7 - Need Advice/Suggestions

Have a Jolida SJ-502A Tube Integrated who's tube compliment is currently (4) Tung-sol 6550, (2) Tung-sol 12AX7 and (2) NOS RCA 12AT7.

Recently purchased a Jolida JD-100 CDP which currently is using (2) NOS RCA 12AX7. The person I bought the CDP from kindly (thanks Colleen) gave me a stash of some 12AX7 tubes which include pairs of EI Elites 12AX7E ,Gold Series Groove Tubes 12AX7-M, and EH 12AX7.

Right now, the Tung-sol in the amp, and the NOS RCA in the CDP sound good, but wondering what other 12AX7 combinations might sound as good or maybe even better? Anyway, was curious about what some of you more experienced "tube rollers" might think would be the best combination of 12AX7 to be running in the CDP and AMP?

All comment appreciated.

Hey Fishboat,

Appreciate your advice, but I'm less interested in going out and buying some more 12AX7 tubes, and more interested in knowing what combination of 12AX7 tubes in both amp and CDP, work well based on the tubes that I have on hand. Guess I should have made that point a little clearer in my orginal post.

Well right now, I'm running the NOS RCAs in the CDP, and the EH 12AX7 (switched out the Tung-Sols) in the amp, and it's sounding pretty sweet. This afternoon I've listen to Robbin Ford, Susan Tedeschi, and Tab Benoit, and it sounds the way I want to hear it. Now how the EH 12AX7 might sound with Allison Krauss or Del McCoury might be a differnt story. But for my more blues orientated material the EH is sounding fine. Definely got that "juke joint" sound.
