What tube pre-amps pair well with Pass amps?

Many years ago , when the X250 was in production, I used a Lector Z.O.E preamp. I think it’s an Italian audio company. Anyway, it sounded really good after trial and error with various nos tubes. I ended up selling it to “upgrade” but it was manhandled during shipping. So sad. Anyway, when my friends come over to hear my new gear a lot of them will compare the new stuff to the Lector/Pass combo , ie , xx isn’t as extended as your old setup. Sort of became a gold standard for them

Anxiously waiting my Nelson Pass Designed Korg B1 tube preamp!  It should be shipping soon: https://diyaudiostore.com/collections/b1-buffer-w-korg-triode-pre-amplifier
I heard one at his place in front of a SIT-3 and an F7 driving Tannoys.  Sublime!

I use my Pass XA-60.8 amps with an AR 5 preamp and YG Kipod speakers and the sound is exactly what I want.  My Digital gear is Esoteric N-01, K-01 and the Brinkman Nyquist II.  I am not a vinyl guy.

The Aric audio preamps seem to be built well with a good circuit design.Can they optimize it for the pass amps when you order one?

@invalid Thanks for the kind words! Offhand, there is no optimization or tweaks needed for any of my preamps to mate seemlessly with any of the Pass amps. I have dozens of happy customers currently using my line-stages with Pass amps without any issue with integration. Feel free to contact me via my website if you have any other specific questions! Best wishes, Aric
