Douk Audio P2-FM Magic 6E2 Preamp, Headphone Amp, FM Radio and Clock

Our verdict

The P2-FM is less a traditional preamp and more a desk companion: 6E2 magic-eye tubes and a VFD spectrum display up top, a preamp and headphone amp inside, and an FM radio, accurate clock and Pomodoro timer built in. At $79.99 it earns its space as a visual centerpiece while handling light audio duties. Headphone power is modest, so pair it with easy-to-drive cans.

Best for
Desk workers who want a glanceable clock and FM radio alongside a warm tube preamp and headphone amp for light listening.
Skip if
You need serious headphone drive above 200 ohms, or headphones and line output running at the same time.

The Douk Audio P2-FM is a desktop preamp and headphone amplifier priced at $79.99, with an unusual twist: it doubles as an FM radio and a desk clock. Two 6E2 magic-eye tubes and a VFD screen react to the music in real time, displaying audio levels in sync with the rhythm from either the microphone or line input.

As an audio device it is a preamp and headphone amp in one. The 3.5mm headphone jack has priority over the line output and drives headphones from 32-200 ohms at up to 50mW into 32 ohms, with an input impedance of 20K ohms, output impedance of 10 ohms, SNR of 98dB or better and THD of 0.003%. Adjustable tube gain and 7 levels of VFD brightness let you tune the display to your room.

The radio section tunes three bands (87-108MHz, 76-90MHz or 65-74MHz) with manual input, auto-scan and up to 10 station presets, backed by a high-gain antenna. As a clock it is rated to within about one minute per year, with customizable font and animation styles and a built-in Pomodoro timer on a 30/5 minute work cycle. One quirk to know: when AUX input is plugged in, only clock and sound-level modes are available, and in radio mode the display shows frequency only. The package includes the preamp, two 6E2 tubes, a DC 12V adapter, an FM antenna and a set of feet.

What we liked

  • 6E2 magic-eye tubes and a VFD spectrum screen visualize audio levels in sync with the music
  • Serves as both a preamp and a headphone amplifier in one small desktop unit
  • FM radio with manual tuning, auto-scan and up to 10 saved stations, plus a high-gain antenna for reception
  • Clock keeps time within about one minute per year with customizable font and animation styles, plus a 30/5 minute Pomodoro timer
  • Adjustable tube gain and 7 levels of VFD brightness for any room

Worth noting

  • With AUX input plugged in, only the clock and sound level modes work; in radio mode the VFD shows frequency only
  • The 3.5mm headphone jack has priority, so headphones must be unplugged to use the line output
  • Headphone drive of 50mW at 32 ohms is modest, and the matched range stops at 200 ohms, leaving high-impedance headphones out of scope
