Most Musical 6NS7 tube for a Preamp?

A request for recommendations by those with experience with different 6SN7 tubes.

My system so far is a Pass Labs XA25 SS Amp, and a circa 1988 Tannoy FSMs.
The speakers operate at 4 ohms with a 94 sensitivity.

The room size is medium. Acoustically well treated.

I listen at lower volumes 60-75db. Vocals mostly.

I am looking for the most musical preamp, with a remote.

Budget is $3k. Used preferred. Better value.

Not considering anything from Schiit Audio.

Considering- Supratek Chardonnay.

Any other suggestions?

Tube Ideas?

Thank you!

I have the UltraVerve and Pass XA25 feeding Focal 1027BE speakers.

I have an XA 25 running with a deHavilland UltraVerve. My volume levels are similar to what you describe.   It is a perfect match for my tastes which are towards tube warmth.  You can roll the 6SN7 to fine tune the sound.  I just this past week rolled from a Sylvania chrome top short glass green label to an NOS black glass oval plate TungSol.  Nice extra is you do not have to worry about matched pairs.  Bass has a bit more punch. Happy before the change and happier now.  Of course, there are so many variables.  In my setup, compared to two prior preamps (an Audio Note M2 and a Vinnie Rossi LIO), the deHavilland is a great match. Both of the other two preamps are very fine products.  It is a matter of how all the variables came together for me.

I know this thread was more about the 6SN7 but another consideration is the preamp gain.  I also listen mostly in the 60-75 dB range. The ability to fine tune the volume has been a challenge for me over the years.  Something to consider.  I am happy with this aspect with the Ultraverve Pass XA25 combo.
