Douk Audio T14-EQ Mini MM/MC Phono Stage RIAA Preamp Review

The Douk Audio T14-EQ, priced at $49.99, is a mini phono stage: it takes the low-output signal from a turntable cartridge and converts it to a line-level signal with RIAA equalization, in an all-aluminum case measuring just 84×84×28mm.

A switch on the bottom selects MM or MC cartridge input (0.005V RMS and 0.0005V RMS input levels respectively). The output stage offers stereo RCA for feeding an amplifier or active speakers, plus a 3.5mm headphone jack rated for 16–200Ω headphones at up to 250mW into 32Ω, so records can be enjoyed directly or quietly at night. Treble and bass controls give ±5dB of adjustment. The RIAA response is within ±0.5dB, with a phono signal-to-noise ratio of at least 80dB, THD of 0.1% or less, and a 0.6V RMS output.

Power comes over USB 5V, which means a computer port or power bank can run it anywhere in the house; a built-in power isolation circuit is designed to prevent common ground noise when other devices share the same power source. Two listing notes matter in daily use: the headphone jack has priority and must be unplugged before RCA output works, and no DC5V power adapter is included, so you need to provide one.

Douk Audio ships worldwide with free and expedited options whose cost varies by destination; packages under 2kg typically travel by airmail (10-25 days) and heavier ones via DHL, UPS, or FedEx (5-8 days), with import duties the customer's responsibility. The unit carries a 1-year warranty, and the 30-day free return or full-refund policy excludes mistaken orders, man-made damage or misuse, and subjective change of mind.
