Again I reiterate thanks for all the work in the review. As can be seen from my spec I listen through Stax electrostatics via the M director and as my previous posted comments show, cannot imagine a purer,more musical sound or more natural vocals. I would love to hear a comparison of these 2 systems i.e. Stax v. M Prime amp. Anyone in a position to do this?
