This small Aiyima B01 amplifier, although compact, benefits from a beautiful design and very good sound performance. Its Class D amplifier stage embeds two TPA3116 chips allowing it to develop a power of 2x50W under 4Ω, with an additional subwoofer output of 100W. In addition, the B01 has many settings on the front panel, to adapt the restitution according to your listening or your audio system. There is a main volume control, level controls for bass and treble, a knob to adjust the frequency of the subwoofer output and a last one to control the volume level of the subwoofer.

In terms of connectivity, the B01 has a Bluetooth 5.0 receiver at the input to stream music directly from a smartphone, as well as an analog stereo RCA input and a USB-A port to connect a storage device such as an external hard drive or an USB key. For its outputs, the amplifier offers of course speaker terminals, but also an output for active subwoofer and another one, amplified, for passive subwoofer.
