SMSL x Rohm
Rohm may not be a household name, but the Kyoto-based electronics manufacturer is sure to make a few fans via the SMSL D300, a desktop DAC that boasts a THD+N of 0.000125% and 118dB SINAD.
Rohm flagship DAC chip
The Rohm BD34301EKV DAC chip supports playback of 32-bit/768kHz with THD+N as low as 116dB.
Rediscover your library in 32-bit/768kHz
Rediscover your favorite songs in 32-bit/768kHz formats. Many of us grew up listening to vinyl records, CDs, or low-quality MP3 files. Compared to these formats, hi-definition lossless formats carry more information and better sonic detail. You won’t believe your ears.
Low jitter across all inputs
Whether you enjoy listening via the USB, coaxial, or optical input, the D300 keeps jitter ultra-low thanks to a CK-03 clock processing circuit. Unlike many DACs, which reserve the best clocking for the USB input, the D300’s CK-03 clock processing circuit ensures ultra-low jitter across all inputs.
Low noise, pure signal
A low-noise power supply and built-in shield keep things quiet inside the D300. So quiet, in fact, that the total harmonic distortion plus noise, or THD+N, of the unit is 0.000125%.
Cut the wires--keep the quality. The D300 has Bluetooth 5.0 with support for codecs like SBC, AAC, aptX, aptX HD, and LDAC. A Qualcomm QCC5125 Bluetooth chip can receive hi-fi music tracks from your laptop, phone, tablet, or other wireless device.
Tempered glass display panel
The D300 uses a gorgeous and durable tempered glass display panel. Transmitting more light than traditional display panels, it can be read from a distance, allowing you to operate it from across your desk or room.
Full-featured remote control
Control the D300 from up to 32 feet away using the included remote control. Adjust the volume, change the input selection, or access submenus--all from the comfort of your couch.
