According to the box it came in, the new cartridge was called the ''HarmonyMg.'' Though constructed of a magnesium-alloy, my pre-production version of the Harmony had a silver polyhedral body (the Discovery is blue) and a different magnetic engine. Robert told me that the Harmony had an Accurate motor in it, which, with its 24K gold coils and finer tolerance parts, represented a considerable step up in quality (and price).

A Short review of the HarmonyMg and Audio Research's Reference Phono preamp.
