Suggest you also try an ARC pre-amp if you can. They have been "known" for building quality pre-amps since the early 1970's. I recently bought a used SP-6A for about $800.00 It is miraculous, and I was using LUX tube pre-amps before that, which were not really "bad."
Just a suggestion. I am sure you will be pleased with whatever you finally buy. Be sure to try it IN YOUR ROOM before you buy if you can.
Cheers!
