Hacking the board to fully separate planes is going to be essentially impossible. It is a multi-layer board with the planes embedded in the stack, there is no way to get in there with a dremel tool to cut a plane without completely destroying the board. I really don't want to put jumper posts in to allow the sections to be separated for the few that want to do that. That significantly adds inductance for the normal case and I don't want to do that. The best bet is to just trust me that I have done a good job of isolation as is and not worry about it. (I know that can be tough for an audiophile) I did a rough estimate of board cost a few months ago, but I don't remember the results right now. I'll have to go look it up later.
