Douk Audio T13 MM Phono Preamp for Turntables with Stereo Headphone Amp and VU Meter Review

The Douk Audio T13 is a compact desktop preamp priced at $99.99 that handles three jobs at once: it converts a moving-magnet turntable signal to line level, amplifies line-level sources, and drives headphones from a 3.5mm jack. It measures 178 x 118 x 55mm and weighs 730g, and its CNC-machined aluminum panel carries gold-plated RCA terminals and durable adjustment knobs.

Inputs are stereo RCA and phono MM, matching turntables, phones, computers and CD players. Outputs are stereo RCA for amplifiers or active speakers plus a 3.5mm headphone jack rated to drive any 16-300 ohm headphone, with output power of 250mW at 32 ohm, 100mW at 64 ohm and 60mW at 128 ohm. On paper the T13 reaches 106dB or better signal-to-noise on the RCA path, 80dB or better on phono, THD of 0.1% or less, and phono response within plus or minus 2dB of the RIAA curve.

The front panel carries a customized full-color VU meter whose backlight color and brightness adjust steplessly, with a dedicated meter driver chip for accurate pointer movement. The built-in AGC algorithm keeps the display readable whether the input signal is low or high, avoiding the blank-or-pegged behavior of simple meters. Inside, a 100K high-impedance input and power-isolation circuits prevent common-ground noise even when the T13 shares a power source with a player. Power comes over USB Type-C at DC 5V with at least 0.6A, so a power bank, phone charger or computer port works fine.

Two operating notes come straight from Douk Audio: the headphone output has priority over the RCA output, so unplug your headphones to get sound at the RCA jacks, and the VU meter displays the level of the input source, meaning the volume knob will not change the pointer's swing range. As mentioned, the box ships without a power adapter.
