Quite likely. They were among the first cables to achieve ultra low inductance by trading off high amounts of capacitance -- causing some amps to oscillate. Mind you this was taking place between 1 and 5 Mhz. Nelson Pass investigated this back in the early 80s when the use of this cable caused his amps to blow fuses. He later added a simple damper circuit to respond to this scenario.
