Who Offers a Highly Musical Preamp using a 6SN7 tube and a remote?

I got some NOS Sylvania 6SN7 tubes for my Freya and they are wonderful. Outshine all the Russian based tubes I had. I also tried a couple Chinese tubes Shuguang but the Sylvanias are the ticket for me

@isaacc7 @jackd  I am in Denver and have a great tech nearby. If/when I improve my preamp game, I'll consult with him about older models. I know he really likes deHavilland. I am saving this thread into my "end game folder" and now really have a star next to Supratek and Aric. And Don Sachs.

I hope to borrow a deHavilland Ultraverve III to compare with my Quicksilver to see what differences I hear. I realize that the rest of my system and room needs to be revealing enough, so I won't prejudge too much if I don't hear a large difference.

I'd be happy to quote you on a custom build.
