At first glance, the Koetsu Rosewood Platinum closely resembles its little sister, the Rosewood Signature, but its body is in fact a darker shade of brown. It has been crafted from solid aged rosewood and then coated with several layers of a translucent lacquer.
The electrical components are meticulously assembled to obtain a perfect magnetic balance and, hence, a finer, smoother and clearer sound quality. The coils are different from other models as they use a high purity (6N) silver plated copper compound. The magnetic system uses strong magnets: 'Platinum Magnets' that are made of a platinum alloy. This hypersensitive motor reacts to the slightest movement of the stylus in the groove. This results in sound quality with great subtlety and precision. The stylus is conventionally fitted to a boron cantilever.
This Koetsu Rosewood Platinum has a relatively low output level, which means that it should ideally be used with a preamplifier of the same remarkable high quality. Franck
