The PS Audio Xstream Plus SC is made of single crystal(continuous cast) copper, and won't break the bank at about $150.00 used. You have to be fast when you see one come up for sale though(they sell fast- there MUST be a reason). (http://www.psaudio.com/ps/products/detail/xstream-plus-sc?cat=power-cables) You can't go wrong with this one.
