Agreed. What about a dongle type connection similar to the cards with breakout boxes? Then you could have optional cables. I jsut don't know how good it would be to have unshielded wires that close to each other though.
I was going to say does it really need 12V? I guess if it's external it would be the easiest. Either way to get a high voltage output, there has to be high enough voltage rails going to the output opamps to allow for headroom. The X-Merian only has +/-8V rails, which is created by a DC-DC conversion of wither the 3.3 or 5V voltage from the PSU. Even using 12V, you still need to have a DC-DC PS conversion to get +/- voltage rails high enough to allow for a high preamp voltage. I guess I answerd my own question.
