I tinkered around with different cables about four years ago, but the only really exotic stuff I tried was a couple cables borrowed from my father-in-law (Magnan Vi analog interconnects, Transparent Music Wave speaker cables). There did seem to be some sonic differences, but I came away feeling like the extreme cost yielded only minor differences and that those differences weren't necessarily better anyway. I'm currently wired mainly with Outlaw and Blue Jeans cables.
