I've just bought a Nagaoka MP-50 that is described as a "moving permalloy" cartridge. Does the permalloy is exactely the same thing as a "moving magnet"? I'd like to know more about this construction.
Sébastien: The operating principle would be that of a moving iron but with increased sensitivity, which could be used alternatively to increase output, reduce moving mass, or decrease inductance.
