Most Musical 6NS7 tube for a Preamp?

How about an Aric Audio Motherlode pre-amp

You could even discuss which Brand of capacitors, Resistors and many other components if you know what you want or like

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!!

-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.

What about a Schiit headphone amp?
