Topic: Product advice - RME + Mac + Solid Drive SD-250

Hi all,

I am looking for an audio interface for a project using 12 SolidDrive surface transducers (SD1) and 6 of the accompanying SD-250 amps. 

For the project I am using 12 output channels from one mac (usb), 96k/24-bit.  The amp has euroblock connectors (more info in the PDF below).

I have two questions:
1. The RME interfaces all seem to be awesome and have more features than I need.  But with many other companies I'm running into a limit of 8-outputs.  Is there an RME product that you would recommend that has the features I need without too many 'extras'?  (Just trying to be a bit budget-conscious.)
2. Has anyone dealt with the euroblock connections before? Assuming I go with an RME interface, is it easy enough to build/buy an adaptor as necessary?

Many thanks for reading, and for any suggestions/hints/tips you can provide.  Very much appreciated.
