A compact yet high-precision DAC with vacuum tube integration
The OA-JC3 is equipped with a ladder-type DAC, which, due to its simple construction, demands high precision. After five years of development, this device has succeeded in maintaining resistor deviation within 0.1% using a highly compact module. The device, designed for high-end audio applications, delivers exceptional sound quality, significantly surpassing the performance of most commercial audio DACs. The inclusion of a 12AU7 vacuum tube further elevates the sound's detail and richness, providing a warm and dynamic audio experience.
In addition, the device supports a variety of advanced audio formats, including MQA and PCM up to 32-bit/768kHz, and DSD515 (PCM conversion). Its advanced circuit design ensures clean signal transmission, allowing for accurate timing signals across a wide frequency range.
