The differences between the new turntable and the original SL-1200GAE are for the most part cosmetic. The SL-1210GAE’s top plate is a dramatic-looking anodized black brushed hairline finish. The operating buttons and the magnesium tone arm are also black-finished. Affixed to the top plate is a numbered 55th anniversary plaque.
... a special badge with inscribed serial number, upgraded insulation and, for the first time, a specially-tuned Nagaoka MM cartridge.
The unique Nagaoka pickup cartridge provided with the SL-1210GAE is a moving magnet type JT-1210 cartridge that was tuned explicitly for the job by a joint team of engineers from Technics and Nagaoka.
The JT-1210 employs a Boron cantilever and is specifically tuned and designed to offer superior performance in focus and detail in comparison to other Moving Magnet cartridges they say. Furthermore, it will only be available together with the SL-1210GAE turntable.
