Though our systems share no common components, I have nothing but respect for all of the choices you have made (with the exception of the Nanotech stuff which I'm totally unfamiliar with, albeit, thanks to Jack Bybee, I am somewhat up-to-date on nanotechnology in general terms).
Being an OTL guy I'd love to hear the Mactone OTL amps, but then again, I'd truly like to hear any of their gear.
You have put together a no-nonsense rig that addresses all of the major issue without going off the deep end of tweakiness. Good job! This one I'd gett off on the exit ramp and make the detour to audition.
