Tube Rolling on PSE HL1 hybrid line stage preamp

I just recently purchased a PSE Hybrid line stage pre-amp. I have heard that tube rolling can make a difference in this preamp. This thing is a real sleeper it easily equalled the Sonic Frontiers Line 3 and sounded much better than the VTL 5.5, Plinius M16, Classe CP-60. I have it paired with Vandersteen MOdel 5 speakers which are the front end of a home theater and 2 channel system. My amp is a Sim Audio Titan. The sound of this combination is awesome but I thought maybe could make it a litter better if someone has had experience with other than the Sovtek 6922's. Any help would be greatly appreciated.

Is this a product of PSE and Dean Klinefelter of Minnesota? I ask because I have not heard much about his products in the last few years.

In response to your question about 6922 tubes, almost anything is better than the Sovtek. I would begin with Mullard, Siemens or Amperex 6922. Not knowing the sound of this product and what tonal change you are after, it is difficult to suggest a specific NOS tube.

Albert Porter,
Yes this is the PSE from Dean in Minnesota.

Dean is a great guy, hope the tube swaps bring the preamp to where you want it. I searched Google but could not find a page for PSE or an image of your preamp.

I'd just in case asked if matching is required. Pretty odd but Sonic Frontiers does...
Please note that 6922 often needs to be matched to itself as dual triode especially if used on output stages.
