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!

atma- Sorry. How much is the MP 1's retail? (That is the 2 chasis, 6NS7
model correct)?

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.

I emailed Kara she is on a Sabatical so hard to try her Ultraverve.

@chorusYes, but the MP-1 is balanced. We make three preamps- in your case the UV-1 is probably the preamp to look at since your Pass Labs amp only accepts single-ended inputs.

if you want to save yourself a few bucks and feel confident enough to rewire your filament voltages, 8SN7 and 12SN7 variants of the same NOS tubes can be found at cheaper prices.

An acquaintance recently found some Sylvania 8SN7 chrometops at a fraction of the going for the regular variant.
