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!

Pleeeease!Audio Research told me the same thing,but tube rolling was very well rewarded.There are some superb NOS tubes to still be had,but be careful about quality and price.I have had varying,but good results with Mullard 6922,Amperex 7308(best based on price),Amperex 6922 PQ(very pricey,but very good),Telefunken(over rated especially re:price),and the fabulous Siemens 6922 CCa(my current winner).The Ediswan 6922/2492,and Ediswan 6dj8/5358 are also fabulous,and I have these as well.
BTW,do a web-search for "Joe's Tube Lore".It is quite accurate,and informative.
Best.
