Tim, you will need a high temperature solder pot (full of silver solder) to properly prepare that kind of wire for termination (it vaporizes the enamel insulation and solders all the strands together all at once.)
My recommendation is that you send the wire back to Straightwire and have them cut and reterminate it to your specifications. It's just not worth the hassle and expense of doing it yourself. Plus you'll have factory terminations which increase the resale value. Also, because of Straightwire's particular cable topology, you can use the same cable to make either a balanceed (XLR) or single ended (RCA) interconnect.
