Best 6NS7 Preamp for a Pass Labs XA25 amp

Don Sachs makes a excellent 6 sn7 pre 
with premium parts options for around $3500 which is a very good deal 
with a Khozmo   Shunt resistor ladder 
attenuator which cost over $400 with remote it’s a true bargain  for this grade of quality.

There is a two month old Sach's preamp on US Audiomart now.

Great, thank you all very much. Just what I am looking for.
One advantage of buying a product marketed for 3 years now.
ARIC 1,650
DON 2,650
DEHAVI 2,995
SUPRATEK 2,300

I heard from a guy with the xa25 who has both the supra
and a s.s. diy kit designed by wayne coburn. cost 200 for parts.
He likes the clarity of the ss more, 
I may do the diy for now and when i miss the remote
too much, buy a solution model.

There are plenty of used low cost solid state preamps that offer “clarity”, if that’s what your looking for. The original post reads “Best 6SN7 Preamp...”

Few or none of those SS kits will match the musicality of a really good 6SN7 tube based preamplifier worthy to match up well to a Pass Labs XA-25 amplifier.
