I am selling my ZMC2.  $450 + shipping.  I switched to a lower output MC cartridge and went to a different SUT.  This ZMC2 sounds and works great.  Specs on Decware's ZP3/ZMC page.

I confirmed with Steve that a ZMC2 can be converted to a higher gain ZMC1 if you are comfortable with a soldering iron.  I was about to make this change when a different option presented itself.
