Tube Rolling In Audio Research Phono Preamp

I have an Audio Research PH3SE phono preamp that currently has three Sovtek 6922's. Audio Research told me not to bother doing any tube rolling because it will change the "voice" and tone of the preamp. However, I keep reading wonderful things about vintage tubes improving the quality of sound in all kinds of gear. I was wondering if anyone has had any experience with different tubes in their phono preamp and which ones they liked the most. Thanks!

I have a an ARC Ref phono preamp, which uses 10 (I think) 6922's. I retubed with NOS Amperex and NOS RCA for the 6L6. The main most immediate thing was a big drop in the noise floor. On top of that the thing just sounds better.... A lot better.

Given this, I have no idea what may happen if you tube roll in your PH3.....
