Raul is correct. I would just add that the wire going to the "ground" side of the RCA plug is the one that should be soldered to pin3. Pin 2 gets the "hot" wire. You can do it yourself, but since Tri is colleagial with Atma-sphere, I am sure he would do it for you, too. I own both a Triplanar and an MP1 myself. I think you will be very happy with that combination and the "right" phono cartridge.
