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!

Sheesh- we don't get in the mix?
I can vouch for Andy Bouwman of Vintage Tube Services. We have many consistently positive comments from our customers going back 25 years.  


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.

@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.
