My ATH-A100ti equips with 6N-OFC cable wire (oxygen free copper wire), and my Sony MDR-CD1700 comes with LC-OFC wire(linear crystal oxygen free copper). The A100ti consists of 99.99997% pure copper, so I'm thinking it would be very nice if I can find this cable and DIY it as an upgrade to my Senn HD-600 cable. I currently have a Clou red, but the stiffness of the cable really turn me off. Do you know whrere I can purchase these type of cable? Thanks.
