Re-Tubing A Sonic Frontiers Pre Amp

Has anybody had any experience re-tubing a Line One, Two or Three? If so, what kind of tubes did you use and what results did you get?

I recently re-tubed my line two with valvos. The bass is tighter and the highs and mid range are quicker. Hope this helps.

He is a true professional that will give you excellent advise (IMHO). He has never let me down.

Detailed, better bass, deeper soundstage, to my ears the "Best". NOTE: Only 2 tubes are needed, no matter if you are using SFL 1, 2 or 3.
