Douk Audio C100 PRO Digital Audio Player 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.

Specifications

How it compares

At $239.99 the C100 PRO sits $30.00 below the Ampapa Q1 ($269.99) and $90.00 above the Douk Audio DAC-Q11 ($149.99). Unlike both, its page lists no computer-USB audio input: it plays files from SD cards, U-disks and hard disks (WAV to 768KHz/32Bit, DSD512, FLAC to 192KHz/24Bit), streams over Bluetooth 5.0 with APTX-HD and LDAC, and takes optical in. The Q1 and Q11 list USB inputs and a two-chip switch; the C100 PRO uses a single ESS9038 and lists a 2.4-inch OLED, a VU meter and balanced XLR outputs, where the Q1 has balanced TRS and the Q11 only RCA and AUX.

The Douk Audio Q100 at $499.99, which is $260.00 more, lists a USB-C input, AES, Bluetooth with LDAC, XLR and RCA outputs, an SNR of 124dB or better against the C100 PRO's 118dB to 119dB, and a built-in AC supply. Who it suits: the C100 PRO fits a listener who wants to play files from a drive or card, with a remote and a display, and feed an amplifier or active speakers over balanced XLR or RCA. The Q11 and Q1 suit a PC-based desk; the Q100 suits the larger budget.
