For the direction you want to go in, which is really aggro and f**ked up, I'm thinking that the best in these early stages would be the Phenol, but make sure you get a format-changer box to convert back and forth from it and the 0-Coast. That's necessary not only because the 0-Coast and Phenol use very different jack formats, but the Phenol needs the interface box to extend its ground-plane to so that it can go on over the 'shield' on the 3.5mm jacks. Yeah...this could get real fun, real quick!
