I have heard that the MI2 can be a problem for some speakers.I have used them and not had problems.One of the better cables.Beats many other higher priced cables.
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.
