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.

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.
