Douk Audio M1FM TPA3116 Digital Amplifier Review

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.

Specifications

How it compares

No other amp in the stereo-amplifier reviews lists an FM tuner. The M1FM costs $99.99 with its 24V/4A supply in the box. That is $40.00 more than the Nobsound NS-15G with its 19V/4.74A adapter ($59.99; $49.99 without one) and $20.00 more than the Douk Audio M1 PRO ($79.99 with its 32V/5A supply). The NS-15G page lists two TPA3116D2 chips with a 100W+100W headline (quoted above 24V at 8A into 4Ω), Bluetooth 5.0, RCA, ±10dB tone controls with bypass, but no FM tuner or remote. The M1 PRO uses a TDA7498E chip at 160W x 2 into 4Ω with Bluetooth 5.0, RCA, a U-disk input and a low-frequency output, again without FM. The Nobsound TONE ($39.99 with a 19V adapter in the box) matches the M1FM's 50W x 2 at 4Ω rating on a TPA3116 chip, with Bluetooth and AUX only.

Who it suits: the M1FM fits a small room or workshop that wants radio, Bluetooth and a remote in one box and drives modest speakers. For a higher power headline and tone controls at $40.00 less with its adapter, the NS-15G is the closer match; for playing files from a USB stick, the M1 PRO.
