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.

Hey Richfield hunter, this is off topic, but you don't mean Richfield PA, do you? Right next to Mount pleasant Mills, McCalisterville, Cocolamus, and of course the city of Evendale?
Albert Porter,
Thanks for the response. I am a novice at this tube thing. I always had solid state only and then Richard Vandersteen kept telling me I needed to experience the Model 5's with tubes and I am impressed indeed. I will call the people you suggested and look for something better. Thanks again for the input.
I agree with Richard Vandersteen about the inclusion of tubes. He has been making "that comment" for several years. It always brings a smile to my face when I hear people still repeating it.

If you should speak with Dean at PSE, have him call me. I would like to know how he's doing.
