From my private collection:World famous and Winner of The Absolute Sounds multi-year Editors Choice Award. Koetsu Onyx Platinum Moving Coil Cartridge This is a treasure that has been kept for years, like new condition, the sound is the best, beautifully crafted with excellent detail, the speed of sound is faster, and the mid-bass is really tightened and solid, wide dynamic ranges, very sweet and musical, stylus still sharp, cantilever and suspension is also in excellent condition. Used under 30 hours. The first non-wooden bodied Koetsu. The body of the Onyx Platinum is machined from a block of high quality Onyx stone. Each block is carefully selected for natural grain and polished to a very fine finish. The use of Onyx results in the cartridge being one of the heaviest at 12g. The coils and cores are very tightly matched among the production models. The Onyx Platinum is also the only cartridge with tapped mounting holes. The Onyx Platinum is very different from the earlier Onyx series of cartridges which do not have the Platinum alloy magnets. This makes for a world of difference in terms of performance. However, owners of non-Platinum Onyxes need not despair for it is possible to rebuild these units with the same Platinum innards as the Onyx Platinum. Every audiophile music lover knows of the legendary sound of Koetsu phono cartridges from decades past. Those old enough to have experienced Suganos Koetsus retain the memory of a musical experience unequaled. Few were privileged to own and enjoy a Koetsu. Many of the converted searched out second and third Koetsus, assuring a long, cherished relationship. Now, in analogs Golden Renaissance and through the efforts of Suganos sons, Koetsu phono cartridges are again available. Though limited in quantity due to their personal, hand built nature, the Sugano family offers a range of models including the Rosewoods, the Urushi, and the ultimate Koetsu, the Onyx Platinum. To fully appreciate Koetsu, we must know Yosiaki Sugano, artist, musician, swordsman, calligrapher, business executive and creator of the worlds most renowned phono cartridges. In his youth, choral singing introduced him to western music, He pursued sword making, dueling, calligraphy and painting, emulating his hero, the 17th century Japanese landmark figure, Honami Koetsu. In postwar Japan, Sugano rose to prominence in one of Japans largest industrial companies, yet continued to pursue his passions, now including hi-fi. In the 1970s, Sugano began to experiment with phono cartridges by substituting his own parts in commercially available models. His keen ear and deductive reasoning, combined with an artists sensibilities, led to the creation of what would become a legend in audio. Sensing the moment, Sugano named his cartridge after his hero, Koetsu. Suganos quest led him to enlist universities, specialized industries and master craftspeople to create the special parts to go into his masterpieces. One of the first to use 4 nines copper (99.99% pure), current production uses 6 nines copper (99.9999% pure). Platinum signature models feature silver cladding of the 6 nines copper, a process where a silver sheath is slowly drawn over the copper conductor. Ultra-pure iron square plate formers were sourced for their most predictable magnetic characteristics and lowest oxidation. Pre-aged to the perfect consistency, rubber suspension parts are sourced under license with a rubber damper manufacturer. Special magnetic materials, including Alnico have been featured. Today, samarium-cobalt is used with platinum magnets reserved for the flagship models. Japanese craftsmen carve the rosewood bodies, lacquer coat the Urushi bodies, or cut stone for the onyx Platinum. Styli are specially designed and precision ground for Koetsu. Today, Suganos sons have revived his art and continue to create musical masterpieces under the watchful eye of the old master. For every music lover, your journey to musical nirvana is incomplete without a Koetsu phono cartridge in your system. Review:The end result is harmonious and cohesive, and the music unfolds in a way that gives you more time to listen – more time to unravel the individual strands that form part of the whole.Hi-Fi+“… the Koetsu endured in delivering boatloads of color and texture, yet at the same time I’ve never heard a cartridge with greater, clearer pitch certainty on even the lowest bass notes ... All in all, the Koetsu Onyx Platinum communicated color, texture, touch, and musical nuance to an extent and in a combination that I’d never before heard ...”Art DudleyStereophileDecember 2018Please watch the YouTube videos:https://youtu.be/3VdB5w0FjG0https://youtu.be/Y_yqaqLeslASpecifications:Body: Onyx StoneType: Moving CoilCoil Wiring: Silverplated CopperMagnet: Platinum MagnetCantilever: Boron CantileverOutput Volts: 0.3mVFrequency Range: 20Hz to 100kHzChannel Seperation: 25db/1kHzInner Impedance: 5 OhmChannel Balance: 0.5db/1kHzRecommended Impednace: 30 OhmCompliance: 5 x 10-6 cm/dyne at 100 hzRecommended: Tracking Force 1.8-2.0gRecommended Load: 75-500 ohmsWeight: 12.5gThis cartridge comes with Original wood box, Specifications, screws, stylus guard.
