I went through Peter at Double Helix (posted some pics a couple of weeks ago), and a few guys have used AphroditeCu49 (sp? I'm on my tablet, running from memory...) with good results. You can buy one new nodded to mini-XLR from Jaben, but they won't mod existing headphones for you, unfortunately. I don't believe Moon Audio nor BTG Audio can do this particular mod... I'm sure there are other places to have it done that I'm forgetting about.
