The Rosewood model has been a long-time favorite, and was the basis for development of the Rosewood Signature and Signature Platinum, along with the Urushi and stone bodied models which followed.  

The key differences between the three rosewood models are the coils, magnets and cartridge mass.

Additionally, the Rosewood Signature Platinum features rare platinum magnets and silver plated 6N copper coils usually reserved for Koetsu's stone body cartridges.

It's the perfect choice for those lusting after the sonics of a stone model but who prefer the look of rosewood.

The Japanese art of Urushi is a tradition dating back 10,000 years.  Urushi natural lacquer, sourced from the caustic sap of the indigenous Urushi trees. The Urushi is applied by the hands of select Japanese artisans.

Apart from conveying the craftsmanship that lies "under the hood", the curing process of the lacquer shifts the body's resonant frequency in a musically consonant manner.

All Koetsu Urushi models use silver clad ultra-high purity copper coils. This process involves a silver sheath being slowly drawn over the copper.

Koetsu's statement cartridges are distinguished by their stone bodies, which are machined from a block of high quality stone. Each block is carefully selected for natural grain and polished to a very fine finish.

Internally, only the most tightly matched silver sheathed copper coils and cores are specified.

Topping off this exotic recipe, rare platinum magnets complete the story, taking the ethereal Koetsu sound to its most exalted state.
