ORSONIC Audio Accessories
As is commonly known, the sounds we hear when we play an analog record are the sounds picked up by the stylus as it passes over the grooves embedded in the vinyl record. However, those are not the only vibrations that the stylus can pick up. Vibrations emitted from the speakers travel through the air and floor, and reach the stylus through the record player itself. This creates noise, and other unwanted effects. We know the struggles you many go through to eliminate this noise, choosing only the highest quality equipment and techniques to remove it, while also trying not to negatively affect the music itself.
Carefully selecting the record player, amps, and speakers, and tuning them perfectly, one by one, is hard work, but being able to hear and feel the sound improvements is one of the pleasures of playing analog records.
Since its founding in 1939, Orbray has been a global leader in precision processing of industrial jewels such as diamond, and has provided products in a wide range of fields, from key parts for audio-visual products to industrial goods.
We have been manufacturing record styli since 1949. To this day, we continue to meet the needs and expectations of audiophiles around the world, fulfilling orders, for sapphire and diamond styli.
In order to meet the high expectations of long-time ORSONIC fans, we have taken full advantage of our strength in precision processing technology for industrial jewels, and have launched a new stabilizer, cartridge spacer, and insulator.
Every step of the process, from growing the sapphire monocrystal, to grinding and polishing, is done in our own factories in Japan.
These products are not just decorative. We have very high standards for the sapphire materials we select for audio accessories. We use the highest optical lens quality monocrystals to bring out the best acoustic performance from your audio components.
We had serious record enthusiasts try out our products.
Characteristics of Sapphire
Sapphire belongs to the corundum family of minerals, and is the second hardest material, after diamond. With its high chemical stability, great thermal conductivity, and high Young's modulus, it is the perfect material for cutting low-frequency noise and creating a clear sound. For this reason, it is also used to make cantilevers. However, until now, it was not possible to make insulators and stabilizers out of sapphire since they required very large diameter crystal.

Original EFG sapphire
Orbray specializes in growing synthetic sapphire crystals, including large diameter sapphire items.
We use a method called edge-defined film-fed growth (EFG) to grow monocrystal sapphire. Due to its high melting point, the crystal is grown at around 2000 deg C. This leads to a highly-homogeneous composition which is one of the features of the EFG method. Using nano-scale polishing and a combination of excellent materials and ultra-precision processing technologies, we have successfully created unprecedented audio accessories.
