6' triple shielded with plastic-braided metal-teflon over copper wire, silver solder with 24k gold plated terminations, tension relieving springs at ends, $12/pair at the Home Depot TV section a few years ago, wonderful results.
As an added bonus, i soldered a third lead to the braided metal shielding and connected
it to the power conditioner's grounding terminal, poor man's balanced cables.
Call me a peasant but they do a wonderful job.
