New era of amplifier raises the curtain renewed “Real-Sound”

New Class-D amplifier with latest device

Thanks to the improvement of semiconductor technology, the integrated device composed of an advanced audio controller IC and two power MOS-FETs fully optimized audio performance was released from International Rectifier, IR in Calif. in 2012. We found the tremendous sound potential of the device and have been seeking to make best possible use of it. The main portion of the amplifier is very compact size PCB and required shortest wiring achieves ideal switching characteristic. Accordingly the sound could be natural and at the same time full of dynamic. And also the amplifier is proud of almost triple higher efficiency compared to semiconductor linear amplifier, the forceful driving power for speakers and superior power saving ability could be easily comprised all together.

Natural & Organic sound of latest AC-DC switching power supply

The efficiency of our new Class-D amplifier is so high (more than 96% at full power) that the quality of the power source has directly much effect on the final driving power and the sound quality of this amplifier. This time we bet the potential of newest switching controller device to surpass the sound of a traditional analog design power supply. And in further pursuit of higher sound quality and more tasty tonal character we adopt newest SiC(Silicon Carbide) schottky diodes, special audio use electrolytic capacitor, custom oil filled capacitor and ultimate quality mica capacitor. It reached at the well damping, also massive low range and also fine transparent mid to high-end fully free from switching noise.

New design and construction of Side-Wood and Insulators

Smooth curve side-wood included insulator is so unique but also realize like as acoustic instrument sound.
Real” Spruce” used for side-wood and real “Maple” adopted for insulator are combined to cut off vibration effectively from the out -side. And it’s exactly the piece of Japanese craftsmanship in historic town “Hida-Takayama”.
