If your amp is overheating to the point of shuting down then there is a problem with the amp, not the cables. I've used several cables with my CA 200 with no problem. This amp does run hot however.
classe and goertz m2 veracity not compat
my experience auditioning goertz m2 veracity speaker cables with my classe ca 200 amp was that they caused the amplifier to overheat and when i spoke to alpha-core (goertz) they said this does occur with some amplifiers.
