The BD34301EKV DAC chip, developed as part of ROHM’s high-grade MUS-ICT™ series representing the pinnacle of audio ICs, emphasizes ‘spatial reverberation’, ‘quietness’, and ‘dynamic range’ – qualities important for reproducing classical music. Original sound quality design technology makes it possible to successfully reproduce the target sound quality by incorporating a circuit in the signal processing block to check for audio quality. At the same time, class-leading low noise and distortion (130dB SN ratio, -115dB THD+N) provide the high performance demanded by high fidelity audio equipment. At last, the customizable digital filter – a key function of the digital signal processing circuit – supports the creation of the ideal sound sought by audio equipment manufacturers.
S.M.S.L has packed impressive performance with the D300 by featuring ROHM's flagship BD34301EKV audio decoding chip at its core. They have professionally adjusted the DAC tuning to take full benefit of it in delivering quality performance. It has full support for high-resolution 32-Bit/768kHz PCM and native DSD512 decoding with the help of an XMOS XU208 high-quality 8-core USB processor.
One can simply feed high-resolution audio signal input to the D300 using a wireless Bluetooth connection. The D300 adopts the latest Bluetooth processor chip from Qualcomm providing it with Bluetooth V5.0 connectivity. It supports high-resolution wireless transmission codecs including LDAC, AptX HD, AptX, SBC, and AAC.
S.M.S.L has featured their new CK-03 ultra-low jitter clock system with the D300. This enables ultra-low jitter for the signal across all the available inputs with the D300 that includes USB, Coaxial, Optical, and Bluetooth. With ultra-low jitter in the output, the output quality is simply top-notch.
S.M.S.L has designed a special discrete component stabilized power supply for the D300. It provides noise-free operation ensuring each component on the analog and digital circuits receives proper power. It is optimized for better efficiency with lower power consumption. To protect the power supply from any outside interferences, S.M.S.L has given it a properly shielded structure.
