I Agree with Ecclectique, Changing 6SN7 tubes is a BIG difference, bigger than changing cables!
I recently went all around tube rolling 6 different pairs:
RCA grey plate is good and will let you know what you are missing but not the best, Sylvania Crome tops are kinda aggressive, I have some flat plates with some brand I forgot which are horrible even if they are NOS....watch out!
