This is what Mr. Dunlavy wrote about his own interconnects;
With respect to interconnect cables, the best-quality ( but modestly priced) ones sold by Radio Shack are among the very best we have measured and used. You can spend a lot more and, believe it or not, get a lot less with respect to such important attributes as capacitance, shielding, mechanically induced noise (piezo-electric properties), etc. Sure, we have designed and sell interconnect cables that are without peer, with respect to important electrical properties, but they are no better, audibly, than the Rat-Shack types within most systems.
