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 currently have a PH-3SE an am using 6h-23 Russian tubes from the cable co. They're very quiet and are comparable to Amperex 7308's which I replaced them with. Sovteks are junk, the only reason AR is telling you that is because that's the tube they use to sell the PH-3's with which they don't even sell anymore. They went to electro harmonix as their stock tube.
Plese don't buy the siemens and telefunkens you see advertised here on Agon. They're very good and deliver exceptional sound but are not worth the astonomical price folks are asking. If people would stop buying these, the price would come down to what they're really worth which is considerably less!
Rodman, It has not come as a shock to me at all. The fact that scare tactics have always been used as a means of getting people to pay more for something than its worth!!
"When these are gone they'll not be anymore" Yeah right.
There'll always be something to replace what's supposely not available anymore, that's what capitalism is all about.
We're paying $3.69 a gal. for gas right now because of a so call shortage of oil, when there's enough oil in our reserves to last for the next 75 to 100 yrs. All the gov. has to do is let some of that reserve oil out for 30 days and the price of gas goes down immmediately.
Keep believing there's no more tubes available and like gas the price will keep going up!
