Industry Leading DAC Chip

The SMSL D300 comes with ROHM flagship DAC chip BD34301EKV, a 32-bit stereo D/A converter integrated with ROHM's own sound quality design technology. Excellent numerical performance is achieved for high-end audio. You can choose your favorite sound quality by switching between two FIR digital filters. Equipped with PCM I/F and DSD I/F, the maximum sampling frequency supports 768kHz and 22.4MHz respectively.

Precise Processing Circuit

The D300 features a brand new CKC-03 clock processing circuit pair with built-in shield to achieve lower clock jitter and improve power efficiency. Besides, they can also reduce consumption and make the clock jitter of the optical and coaxial as excellent as USB.

Low Noise Power Supply

The SMSL D300 follows with low noise power supply featuring the specially designed discrete component. With built-in shielding, the power supply can be stabilized. And the multiple low-noise stabilized power supplies can provide low-noise power supply for analog circuits.
