I'm using one I made from CryoMax III wire and Furutech FI-11(ag) IEC and FI-11M (cu) AC connectors. I've built a ton of these for myself and friends with no complaints yet and they DEFINITELY sound better than the stock cord on my Calypso at cost of ~$100 or so. The parts are available from CryoParts (no connection, just a satisfied customer).
