Anyone rolled tubes in an ARC Reference 3 preamp?

I agree that introducing vintage 6DJ8 family tubes in, say, an ARC PH7 phonostage, can yield a much broader range of results (almost all favorable) than rolling 6H30s.

I did a comparo of stock 6H30-EB, cryoed 6H30-EB, and 'NOS' 6H30-DR in a CJ ACT2 and in the phase inverters of a CJ Premier 140. The DRs came from Evgueny at ConusAudio. Did I hear a difference? Yes. Was it significant? I don't think so. Maybe ... maybe ... a little more top end extension. Changing the Premier 140's single 6922 driver tube made a larger audible difference than rolling the 6H30 in either it or the ACT2.

John, when you return to the dark side (a non-6H30 based preamp) some day, you will have to make it more accessible to get to the tubes. Somehow I think tube-rolling is in your blood. 8-) And you can secure the top cover with a couple strips of duct tape. All those machine screws are a pain indeed!

I've considered that, but I'm afraid I'd lose the screws! :-)
