The Douk Audio M1FM is a HiFi digital amplifier with a built-in FM radio, priced at $99.99. It combines a stereo power amplifier, a Bluetooth receiver and an FM tuner in one compact chassis, aimed at desks and shelves where a full-size receiver would not fit.

The amplifier section uses the TPA3116D2 chip, rated at 50W x 2 into 4 ohms, which the maker says easily drives all 3-8 ohm passive speakers. Bluetooth 5.1 covers SBC, AAC, aptX and aptX-HD with 24-bit/48kHz lossless transmission, and the FM tuner spans 76-108MHz with automatic and manual search plus good anti-interference for weak stations. Measured specs include THD+N of 0.03% and SNR of 102dB or better.

Inputs cover Bluetooth, FM, stereo RCA and AUX, with outputs to banana speaker jacks and a 3.5mm AUX line output for connecting another amplifier or active speaker. A display shows the working status in real time, the full-function remote handles every setting from across the room, and a one-click Bluetooth reset clears all paired devices. Four NE5532 op-amps sit in pluggable sockets, so swapping them is part of the fun. The package includes the 24V/4A power supply, Bluetooth and FM antennas and the remote control - just supply the remote's 2 x AAA batteries yourself.

Douk Audio ships worldwide with free and expedited shipping options at varying cost by country. Packages under 2kg travel by airmail in roughly 10-25 days, while orders over 2kg ship via DHL/UPS/FedEx in about 5-8 days, and any import duties or customs charges are the customer's responsibility. Returns are free within 30 days for a full refund, and every item carries a 1-year warranty. Exclusions cover orders placed by mistake, man-made damage or misuse, a change of mind, and anything outside the warranty terms.

What we liked

  • Amp, Bluetooth receiver and FM tuner in one box - stream wirelessly, tune radio or use the RCA/AUX inputs
  • TPA3116D2 chip delivers 50W x 2 at 4 ohms, driving most 3-8 ohm passive speakers
  • Bluetooth 5.1 supports SBC, AAC, aptX and aptX-HD with 24-bit/48kHz transmission
  • FM reception covers 76-108MHz with automatic and manual search and effective capture of weak signals
  • Full-function remote control, status display, one-click Bluetooth reset and four pluggable NE5532 op-amps for easy upgrades

Worth noting

  • The remote requires 2 x AAA batteries that are not included
  • Higher performance needs a larger power supply than the included 24V/4A unit - the maker says to prepare one yourself
  • The 3.5mm AUX output is line level for another amplifier or active speaker, not a headphone jack
