*These are my own works and are currently being sold. A kit assembly product for a super sampling DAC featured in the 2018/10 issue of “Transistor Technology” published by CQ Publishing. Transient response waveforms without the “echo noise” inherent in conventional digital filters can be reproduced (Murakoshi Yoichi)
Maintenance information: 2023.11.29 sound confirmed
Accessories: Assembly manual, operation manual (both copied)
Main specifications: 64x super sampling method compatible format 44.1 kHz to 96 kHz/24 bit
*Currently on sale is Yoshidaen's original DA converter. By adopting the ESS ES9018 DAC chip, a precise, delicate, and gorgeous sound is reproduced. Since it can also be used as a CD transport or DAC for digital devices, it is finished as a DAC with high cost performance in terms of sound quality and functionality. There are line scratches on the top plate and circular stains on the back (Kojima Yosuke)

It is a D/A converter equipped with a high-bit digital filter and a high-bit D/A conversion system. Noise generated when switching between digital signals is eliminated, and separation is improved by making the left and right independent configurations. The sampling frequency automatically follows 44.1k/48kHz, making it useful as an independent DAC for CDs and DAT. There is dullness and dirt over time (Sasaki Shota)
