ORSONIC Audio Accessories

As you are well aware, 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 picked up the stylus. Vibrations emitted from the speakers travel through the air and floor, and reach the stylus through the record itself. This creates noise, and other unwanted effects. We know the struggles you go through to eliminate this noise, choosing only the highest quality equipment and techniques (Be careful not to remove too much noise, as it may negatively affect the desired sounds).
Carefully selecting the record player, amps, and speakers, and tuning them perfectly, one by one, is hard work. But when you hear and feel the sound improvements, this is one of the pleasures of playing analog records.

Since its founding in 1939, Adamand Namiki has been a world leader in precision processing of industrial jewels such as diamonds, and provided products in a wide range of fields, from key parts for audio-visual products to industrial products.
We have been manufacturing record styli since 1949. From sapphire styli to diamond styli, we continue to meet the needs and expectations of audiophiles from around the world, receiving and fulfilling orders, even today.
In order to meet the high expectations of long-time ORSONIC fans, we have released new "Stabilizer," "Cartridge Spacer," and "Insulator" products, taking full advantage of our strength in precision industrial jewel processing technology.
From growing the sapphire monocrystal, to grinding and polishing, every step of the manufacturing process is done in our own factories in Japan.

These products are not just decorative. They are the highest optical quality monocrystals that can bring out the best acoustic performance from your audio components.
We have very high standards for our sapphire materials that are selected for audio accessories.

We had serious record enthusiasts try out our products.

This is what they had to say.
  • The world’s first sapphire audio accessories
  • Disrupting the audio industry

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 velocity of sound due to the high Young’s Modulus, it is the perfect material for cutting low-frequency noise and creating a clear sound. This is also the reason it is used to make cantilevers.

Original EFG Sapphire

Adamand Namiki is an expert in growing synthetic sapphire crystals, including large diameter sapphire items.
We use a method called the Edge-defined Film-fed Growth (EFG) Method to grow monocrystal sapphire. Due to its high melting point, the crystal is grown at 2000 deg C. This leads to high composition homogeneity; 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 succeeded in creating audio accessories that have never existed before.
