DNM Cables?

I have a set of interconnects and a single run wires from DNM. The speaker wire is ran into the VR'2s speaker single run with a stock silver jumper. I contact VR's company about speaker wire setup and they recommended that the speaker should be ran biwire or shotgun. Has anyone had any experience with the DNM line running bi wire setup? If so, whats your take. I put these cables up for sale on ebay but now I am having regrets and I may pull the plug and give them a try in a bi wire setup.

Since the DNM line is a low price cable I was mislead to think that they are inferior, however, I do believe I misjudge them.
