Douk Audio C100 PRO Mini Digital Audio Player, Hi-Res Music Streamer and Preamp, 384K / DSD Review

The Douk Audio C100 PRO is a mini digital audio player, music streamer and preamp priced at $239.99. It is a source component: it reads or receives digital audio, converts it with an ESS9038 decoding chip, and feeds your amplifier, active speakers or headphones downstream through RCA and balanced XLR outputs and digital coaxial and optical outputs.

The converter section is the core of the value here. The ESS9038 achieves 0.0005% ultra-low distortion and a 119dB signal-to-noise ratio, and the player supports WAV digital audio up to 32-bit / 768kHz plus ISO, DFF and DSF files up to DSD512 on the PRO model. Standard FLAC goes to 192kHz / 24-bit, APE and MP3 to 48kHz / 16-bit, and DTS is supported with two-channel front left and right output. On the wireless side, a CSR8675 Bluetooth chip covers APTX-HD and LDAC at 24-bit / 96kHz for lossless-quality transmission, and Bluetooth input can display lyrics on the screen in sync.

Input options go well beyond streaming: optical, U-disk, hard-disk and SD card inputs all feed the player directly, with plug-and-play reading of digital files. The C100 PRO runs eight languages (Chinese, English, French, German, Japanese, Vietnamese, Spanish and Russian), and the VU meter can display either internal signals or external sounds via microphone pickup. A 2.4-inch OLED screen shows working status, touch buttons and an included remote handle control, and screws on the bottom adjust the VU meter sensitivity. All outputs work at the same time, and the volume button sets the level for every output together.

Douk Audio notes three practical points: the remote ships without its 2 x AAA batteries; DTS output is limited to two channels; and because all outputs play simultaneously, you will want to plan your connections accordingly. The compact chassis is designed for desktop use where a full-size player will not fit.

Douk Audio ships worldwide with free and expedited options, and the cost varies by destination country.
