Recommending a tube preamp for Linn amps/speakers

I have heard them with Audio Research and have been quite impressed with the speakers. But I think cables play a roll too.

Thank you all for your input.
When I searched this subject, I found a series of posts by "lugnut" several years ago. He had previously been using solely Linn gear running active, then inserted a tubed preamp and was quite taken by the degree in improvement. Initially w/ Audible Illusions, Cary(?) then Supratek. He was careful to match output voltages between the preamp & amps - Linn LK140's have 23.5V output voltage.
Given this was several years ago, I was wondering if anyone
had tried a tubed pre in a Linn system since, and could offer any suggestions. VTL 2.5 was offered as a good candidate ... any others ??
Appreciate all suggestions and responses - thank you !

Anubis, changing to a tube amp will do the most for sound. I added the Cary SLP98P to an all Linn system, then a Cary CAD 120's amp and it made all the difference in the world. It worked well with the Katans, Ninkas, Majik 140's, and all of the Klipsch speakers that I had.

I had a Kairn and 2 Klouts but not active and actually used just one.

I had someone come by to buy a pair of Klipsch Lascala's and he brought a vintage tube amp. Shocking!

Dead quiet tube amp.

The problem is Linn uses dirt cheap parts in the crossovers. I had 5140's.
Almost afterthought parts quality. Maybe to make the jump to acktiv better?

You can try vintage tube pre or integrated on the cheap?

I sold my Kairn phono and and still have the vintage tube amp heavily modded though, but still have Linn sources LP12 and Karik/Numerik.

Check out the Mystere CA11 tube preamp for $1795 new. Awesome unit! I bought one to replace my Primaluna Prologue Three. Very satisfied with value proposition offered by this company. Hard to beat in this price range.
