Douk Audio DAC-Q11 USB DAC Review

The Douk Audio DAC-Q11 is a desktop digital-to-analog converter priced at $149.99. It accepts PC-USB, coaxial and optical inputs and outputs to two groups of stereo RCA and two groups of AUX connections, in a CNC-molded case with a glass window on top that shows off the internal structure.

The headline feature is patented dual DAC chip switching - the maker calls it a world first. Two chips, the ESS9038Q2M and the AK4493, can be toggled so you can enjoy either the robust dynamics of the ESS or the refined tones of the AKM. There are three working modes with two different sound effects, supporting simultaneous output of either chip to groups 1 and 2, or the AK4493 to group 1 while the ESS9038Q2M feeds group 2. Measured performance is excellent: SNR of 117dB or better and THD of 0.0003%, with PC-USB handling 32-bit/384kHz and DSD256 for high-resolution files.

Two OLED screens display real-time sampling rates, volume levels and decoding chip status, and a large volume knob handles delicate level adjustments. A remote control adds convenience, and the CNC integrated molding with anodizing keeps the design modern. A few practical notes from the manufacturer: the remote may ship without its 2 x AAA batteries, Windows 7 recognizes the PC-USB input only after installing the driver (other systems need a driver only for DSD playback), and the volume setting applies to all outputs since the two RCA and two AUX groups are controlled simultaneously.

How it compares

At $149.99 the Q11 costs $120.00 less than the Ampapa Q1 ($269.99), whose page calls the Q1 a successor to the Q11. Both are switchable two-chip DACs with a 12V adapter in the box. The Q11 lists PC-USB, coaxial and optical inputs, PCM 32bit/384KHz and DSD256 over USB, RCA and AUX outputs, THD+N 0.0003% and an SNR of 117dB or better. The Q1 lists PCM 768KHz/32bit and DSD512, Bluetooth 5.2 and USB-C, balanced TRS outputs and a 1000mW headphone jack, THD+N 0.0002% and an SNR of 120dB or better.

Cheaper routes: the Douk Audio K5 at $79.99, which is $70.00 less, pairs one ESS9038Q2M with USB and optical inputs, PCM 384K and DSD256, and a headphone amp (560mW at 32Ω on its 6.35mm jack), but has no chip switch. The Nobsound Q4 at $49.99, $100.00 less, lists Bluetooth 5.0, USB, U-disk, optical and coaxial inputs but PCM only to 192K (96K over USB) and 110mW at 32Ω for headphones. Who it suits: the Q11 fits a desk that wants to compare two DAC chips and feed two RCA output pairs at once without needing a headphone amp. The K5 suits a headphone user; the Q4 suits a Bluetooth source on a small budget; the Q1 suits those who want more formats and balanced outputs.
