True Diamond delivers
unprecedented quietness and resolution
Diamond has excellent physical properties such as sound speed and hardness, making it the most suitable material for diaphragms. Its particularly excellent bending rigidity contributed greatly to the realization of the "ultra-low distortion DU" we aimed for this time. When observed with a laser displacement meter, even hard metal diaphragms deform in various directions, causing distortion, but in the case of diamond, its bending rigidity makes the displacement extremely small, suppressing the noise generated on the diaphragm surface. Its particularly excellent bending rigidity contributed greatly to the realization of the ultra-low distortion DU we aimed for this time. This product uses "True Diamond", which manufactures diamond foil by crystallizing diamond on silicon and then melting the silicon.
Diamond has a specific gravity of 3.5, which is about twice that of beryllium, and there was a problem that film-based edges would roll due to their weight. In addition, with general edge materials, it is unavoidable to avoid the problem of resonance at certain frequencies. To solve these problems, we adopted a special polyurethane. Conventional polyurethane had the disadvantage of being prone to deterioration, but this material overcomes this weakness. It is lightweight and highly elastic, and solves the conflicting problems of ease of movement and prevention of unnecessary resonance.
Through the development of the above diaphragm material and manufacturing technology, the newly developed DU equipped with a diamond diaphragm has achieved an astonishing distortion rate of less than 1/100 of the conventional model in the frequency range below 100Hz.
By reducing distortion in the ultra-low range and improving the amplitude frequency response of the ultra-low range, the reproduction of the low range has been improved to an unprecedented extent, and the overlap with the delicate and gorgeous mid-high range with good transients has also been reduced. While reproducing a huge amount of musical information with overwhelming resolution, it also achieves an amazing sense of separation that allows you to feel whichever band you focus on. In addition, since there is no distortion at all, the silence of the silent parts of the music is felt more strongly, and each sound stands out even more.
The housing is made of precision-machined, highly rigid stainless steel. It is designed to firmly support the driver and suppress unnecessary vibrations, resulting in clear sound contours. The housing is also treated with a wavy precision cutting process called "Côtes de Genève." This is a sophisticated technique that is often used for the internal parts of luxury watches, not just for aesthetic reasons, but because the cutting surface is the finished dimension as is, compared to polished finishes, there is less deviation in precision.
No adhesives are used for assembling the housing or attaching the DU, but rather screws, which are difficult to design, are used, making long-term repairs possible. In addition, the fastening force of the screws firmly supports each part, suppressing unnecessary resonance.
The comfort of earphones is determined by the feeling of pressure. Although the method of holding the earphones by using the resilience of silicone, such as selecting an organic shape that promotes ergonomics, may seem correct at first glance, it always puts pressure on the ears, which can unconsciously strain the ears and cause fatigue. Compared to a shape that contacts the ears with a large organic surface, we aimed for a fit without a feeling of pressure by limiting the contact area. Therefore, it fits the ears of many people. If there is no feeling of pressure at all contact points, you will feel how comfortable the earphones are to wear, and it is an excellent fit that feels like a customized earphone. In addition, the housing size is smaller than the A8000, so it fits even easier in the ear.
This product was developed in collaboration with Junkosha, which is famous for developing and manufacturing cables that pursue the transmission speed of signals for the supercomputer "K". The wire material is silver-coated OFC wire that brings together the know-how that Junkosha has cultivated over the years under the Junflon brand, and the insulation coating is ePTFE (expanded Teflon™), which boasts an even lower dielectric constant than conventional PFA (fluoropolymer). Everything is specially designed for the A10000. The
MMCX connector has been redesigned to be even more reliable than the previous in-house developed product. Since the 2PIN relies on the springiness of the pin itself for removal force, it is difficult to make it durable due to its structure, so MMCX is used for long-term reliability.
*The MMCX connector of this model is a high-precision product and is designed to be particularly difficult to insert and remove. We do not recommend re-cabling or inserting and removing terminals for purposes other than replacement due to failure.
This product comes with two types of earpieces, "FUSION-G" and "TYPE E", both in five sizes: SS/S/M/L/LL.
FUSION-G
The triple hybrid structure combines three materials: ultra-density foam, soft silicone, and high-elasticity silicone, to achieve high sound insulation and a comfortable fit without any pressure. The
"ultra-density foam" has a thin design and can be worn without crushing it with your fingers. This reduces the feeling of pressure and achieves high sound insulation. In addition, since it uses the same shape as the silicone type, it is less likely to change the sound quality tendency, and brings out the original sound quality of the earphones you are using.
TYPE E
Two types of silicone material with different hardness are used for the sound guide tube part and the part that touches the ear. The sound guide tube part is made of silicone with a higher hardness than the part that
touches the ear, and grooves are applied to achieve both strength and flexibility. The part that touches the ear uses soft silicone to achieve a comfortable fit and high sound insulation. One earbud is grey and the other is red, making it easy to distinguish between left and right even in dimly lit places by simply pulling the earpiece back slightly to check the colour of the earpiece's earbud.
The opening of the dust filter may become dirty due to earwax, etc. With the A10000, the dust filter is designed to be replaceable by the customer, and is included.
*The product is shipped with the dust filter already installed, so there is no need for the customer to install it separately when opening a new product. If the dust filter becomes dirty after using it for a while, please replace it with the included dust filter yourself. Please refer to the instruction manual for replacement instructions.
