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 recommend the Shuguang Treasure CV181-T/6SN7.
I use them in my Don Sachs preamp. Lot's of resolution top to bottom, meaty and musical...it’s also quiet and reliable. I think it looks great too.

But don’t take my word for it. Don Sachs has every holy grail version of the 6SN7 tube and he says this one kills every one of them.

Apparently the newer Shuguang WE6SN7 is a little bit better. I have listened to this one too but not long enough to hear the difference. It sounded just as good to me. It is a bigger tube and may not fit in all applications.

I've tried a bunch of 6SN7s over the years for the driver in my monoblocs.  Finally settled on the Psvane Globes from Grant Fidelity. Initially bright, they took 20 hours and more to level out and open up. They are excellent with great transparency and tone. 
Wow you guys are a true fountain of knowledge!! Thank you!!

-Kara Chaffee of deHavilland is taking a sabatical
currently with no know date of return.

-The newer LTA that was available on USAudio sold today. Coach?

-Auric is a dedicated purist who does not seem to do remotes.

Coach-I will be waiting anxiously to hear your thoughts on the
new LTA coming your way!! Meantime I will read up on the battery
model.

Aric audio makes a 6sn7 preamp called the Special which can be ordered with or without a remote. The remote version is $3250 I believe. I own the Special and love it. Should i need to replace my BEL 1001 MK5 I am also considering the Pass XA25.
