Description

The D300 is an excellent addition to the SMSL Audio DAC line-up, featuring high-quality materials and Rohm's flagship DAC chip.

Detailed design for excellence

Use Rohm's flagship DAC chip BD34301EKV, and fully optimise performance to make its THD+N as low as -116dB. USB uses XMOS XU-208, a real 32bit USB solution, PCM supports up to 768kHz and DSD supports up to DSD 512.

Professional circuit design

The new CK-03 clock processing circuit, in order to achieve ultra-low clock jitter, makes the clock jitter of fiber coaxial as excellent as USB. 

Built in shield

Built-in shielding, low noise power processing, while improving power efficiency and lower power consumption.

Low noise power supply

The specially designed discrete component stabilised power supply and multiple low-noise stabilised power supplies provide low-noise power supply for analog circuits.

Qualcomm's latest Bluetooth chip

Qualcomm's latest BLuetooth chip supports SBC, AAC, aptX, aptX HD and LDAC.

High-quality materials and design

The D300 features high-quality gold-plated input and output connection terminals, newly designed high-quality knobs, a high resolution fully-fitted colour display screen and screen-off function, a tempered glass display panel giving higher light transmittance and longer service life, and comes equipped with remote control.

The D300 holds Japan Audio Association (JAS) Hi-Res certification.
