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 concur with Chris. I have a PH3SE modified by GNSC and have used Funken's and Siemens to wonderful sonic results. Now, the PH3 is packaged and put away as i have aquired a REF Phono that has been considerably modified by GNSC. V-CAPS tefelon and Caddock resistors throughout. Elna filter caps etc...ect....

I use Amperex 7308 PQ white label, RCA Blackplate 6L6GC and Phillip Miniwatts metal base 5AR4 in the power supply.
Svotek 6922 are probably the worst sounding signal tubes ever made. Anything else will beat those sonically.
