Naim does NOT want owners of their power amps to use high-capacitance speaker cables because it can cause instability to the point of oscillation which can be destructive to their amps and to the tweeters in speakers. Naim does not use any inductors or "snubber" networks on their amps which makes them vulnerable to highly reactive loads.
Some years ago, Threshold amps were self-destructing when high-capacitance Polk Cobra cables were used. Nelson Pass, who was with Threshold at the time, worked with Matthew Polk and they both found that "snubber" networks on the amp outputs solved the problem. Polk received a patent for his efforts.
