Best 6NS7 Preamp for a Pass Labs XA25 amp


Will need a remote.
No SCHITT Kit.
There must be a couple happy XA25 Amp owners out there?

Hi Gadios. Nice amp. I have not heard this preamp myself and it does not use the tubes you are looking for, but Herb Reichart wrote a glowing review on the Rougue Audio RP-7. If you did not know, the XA25 has been Herbs reference amplifier for many years now.

I recently purchased an Aric Audio Special all tube preamp. I am very pleased with it. I am considering the XA25 as a SS amp to replace my BEL1001 when the time comes.

Aric's preamps are all tube rectified, regulated, with 6sn7 output stage. They have variable gain, low output impedance (300 ohms), and high input impedance (100K ohms).
