Lets hear from Fosgate Signature Phono Preamp owners

I think what is happening is that, while the Gold Lions are very quiet, they take on a bit more of the gain than the pre was designed for. That means less gain from the V3-V6 tubes. The result is somewhat less transparency than with the Chinese tubes. I only ran them for about 6-8 hours.

So I put back the originals and will experiment later with the Gold Lions in only one of the V1, V2 positions.

I'm also testing out a NOS Telefunken smooth plate in the V3 position.
