SS Pre Recommendation

I agree with Tvad as I am a Klyne owner and think it should be on your audition list.

I have a Klyne SS pre, SK6* that I'm considering parting with. Feel free to contact me with questions.

Tom Evans Vibe is worth a try. Add the Pulse power supply to improve the bass even more. See reviews in HiFi+ and 6Moons.

I am currently listening to a Belles 28A preamp that is excellent.
It has the tightest fastest bass of any preamp I have tried and owned, and it also has the best soundstage and imaging I have heard, even better than a Modwright 9.0 (tubed) preamp that I also own, although the Modwright is very good the Belles is world class in these areas. I may sell the Belles (which is mint). Comes down to system matching.

I'm in the same situation, trying to find a better pre than exists in the AA Prestige SACD. I've tried the ARC Ref 3, the ASL Flora and the ModWright 9.0SE. The Prestige is in my opinion more open with more depth than any of the above. The Ref 3 was notably the least impressive in that it was truly lifeless after almost 500 hours of break in. The Connoisseur has been highly recommended as a worthy candidate. I do agree with the gentleman that the Prestige has a bit of boom in the bass.
