Ampapa A1 Mini 5654 Vacuum Tube Preamp / Phono Turntable Amplifier with Tone Control

Our verdict

The Ampapa A1 is a $129.99 mini tube preamp that does three jobs: it converts an MM turntable signal to line level, amplifies line sources, and drives 16-300 ohm headphones. JAN5654 tubes in pluggable ceramic sockets deliver the warm analog sound the brand promises, and treble and bass knobs shape it to taste. It is a strong entry point for the Ampapa brand, with the usual caveats: MM cartridges only, 3.5mm headphone output, and shared controls between the two outputs.

Best for
Vinyl listeners who want an MM phono stage, tube line preamp and headphone amp with tone controls in one compact box.
Skip if
You use a moving-coil cartridge or need a 6.35mm headphone jack with higher output power.

The Ampapa A1 is a vacuum tube preamp, phono preamp and headphone amp priced at $129.99, and it is the first product designed by Ampapa, distributed through Douk Audio. It is built for desktop and small-space hi-fi: an MM phono stage converts turntable signals to line level, a stereo RCA input handles everything else, and a 3.5mm headphone jack adds private listening.

The phono stage uses low-noise integrated circuits and high-quality components for clear record playback with an input level of 0.005V RMS and response within plus or minus 2dB of the RIAA curve. The line path accepts 0.775V RMS over stereo RCA, applies the tube stage and outputs 1.5V RMS to amplifiers or active speakers. The JAN5654 tubes give what Ampapa describes as a warm, fine sound that improves detail, transparency, immediacy, richness and dynamics, and because the ceramic silver-plated sockets are pluggable, the tubes can be replaced with 6J1, 6K4, 6J5, GE5654W, 6J1N, 6J2N or 6A2 types directly.

A treble and bass tone control lets you tailor the sound, and a dedicated headphone amp circuit built on two NE5532 op-amps drives 16-300 ohm headphones with 125mW at 32 ohm, 62.5mW at 64 ohm and 30mW at 128 ohm. Total harmonic distortion is 0.1% or less. The RCA output and 3.5mm headphone output can run at the same time, with one set of volume, treble and bass controls governing both.

Inside, the A1 uses solid aluminum alloy knobs and a distinctive case decorated with warm orange and cool green lights. It measures 20Hz-20kHz within plus or minus 0.5dB on the RCA path and ships as a compact desktop unit with high-end component choices behind an eye-catching face.

What we liked

  • A complete front end in one box: MM phono conversion, line preamplification and a headphone amp with 2 x NE5532 circuitry
  • JAN5654 tubes on ceramic silver-plated pluggable sockets, rollable to 6J1, 6K4, 6J5, GE5654W, 6J1N, 6J2N and 6A2 types
  • Treble and bass knobs plus a headphone output make it flexible for vinyl and desktop listening alike
  • RCA and headphone outputs can work simultaneously with shared volume, treble and bass control
  • Ampapa's debut product, made in the same family as Nobsound / Douk Audio with authorized distribution

Worth noting

  • The phono input is MM only, so moving-coil cartridges are not supported
  • The headphone jack is 3.5mm and shares its volume and tone settings with the RCA output
  • The headphone output power is modest at 30mW into 128 ohm, so very demanding headphones may want more

Questions before you buy

Does the A1 work with my turntable?

It has a Phono MM input with 0.005V RMS input level and RIAA-accurate response, so it suits moving-magnet cartridges. Moving-coil cartridges are not supported.

Which tubes can I roll into the A1?

The pluggable sockets are compatible with 6J1, 6K4, 6J5, GE5654W, 6J1N, 6J2N and 6A2 tubes, which can be replaced directly.

Can I use the RCA output and headphones at the same time?

Yes. The stereo RCA output and 3.5mm headphone output can work simultaneously, with volume, treble and bass controlled together for both.

What is the return and warranty policy?

Douk Audio offers a 30-day free return or full refund and a 1-year warranty. Exclusions include orders placed by mistake, man-made damage or misuse, and subjective change of mind.
