His current offerings are getting very expensive, mainly because of the Acrolink connectors. Look on Audiogon for used ones, or email Michael to see what demo or trade-in cables he may have available. He is now getting some older cords with Furutech or Oyaide connectors back for upgrade to Acrolink, and he'll let them go for a good price. I got six cords for $250ea (three gain, three source, all silver/oyaide) in this manner.
I also still have three copper/furutech cords back from when I had my dCs stack. They are 99% as good as the silver/oyaide.
