Matching phono stage to low-output SET pre and mono amplifiers -- Korneff

Folks,

I am looking to upgrade the analog end of my system.  As I look for a phono stage to link into my Jeff Korneff preamp and Korneff 45 tube monoblock amps I want to make sure I'm matching components properly.  I had a George Wright phono and in moving to upgrade I'm unsure of what technical characteristics I need to be mindful of (if any).  If you have these components or have experience matching a phono stage to a 45 tube amp (or low output SET amps) I'd appreciate hearing of your success.

Best,
