Analysis Plus pro cables are  fine precision intruments and should be treated that way.  Many cable companies treat their cables like a commodity. They will replace the cable without looking at it, because they make the cables for pennies. We are not that type of cable company.   We seldom see our cables fail. The connection can fail when people trip or jerk on the ends of the cables and cause damage to the connector, if this is the case we will fix the connector for a fair charge as listed on our website under connectors.
