You have a fine system. The Pass X0.2 is a great preamp. If you just want to change call Wayne Colburn to see if you can get some synergy to the XA60.5 with the Pass X20 or later. Changing the X0.2 will not improve your imaging. I would suggest to redo your room setup and room treatment.
Itching to upgrade preamp...
I'm thinking the preamp might be the weak link at this point... Today I'm using a Pass X0.2 preamp.
The rest of the setup:
Pass XA60.5
Audio Physic Avanti III
PS Audio DirectStream Sr (with bridge2)
PS Audio PerfectWave transport
All interconnects are Cardas Clear XLR. Speaker cables are Cardas Clear Beyond. Power cords are Cardas Clear to everything except amps, which is Clear Beyond. All power is through a PS Audio PP12.
I'm thinking i may want to try a tube preamp with this... although I'm open to solid state as well
