I have several different cables which I use with Auteur. Desktop is either a Silver or Black Dragon. Portable is either ZMF OCC or Lavricables pure silver. Note that the OCC cable is different than the OFC cable he offers. Visually, it looks like this one: from this ZMF product page: http://www.zmfheadphones.com/zmf-cables/atmos Honestly, I don't hear that much difference -- changing portable sources (Cowon Plenue 2 vs Opus #2) is a bigger change. Swapping pads (Auteur perf vs Eikon perf) is a bigger change. As was pointed out to me in a different cable discussion, cables are passive devices. This means that they can only filter the signal. So when someone says the OFC is 'quite dark' they're really saying that the OFC cable attenuates the high frequency component of the signal significantly.
