The Aiyima A8 is a small Class D amplifier that is powerful, efficient and affordable. It is based on an Infineon MA12070 amplifier chip and a NE5532DR PDO, allowing it to deliver 2x55W of power at 4Ω, with rich and dynamic sound reproduction. The front of the device incorporates a central volume control knob. At the back, there is a stereo RCA input and output, as well as an output on speaker terminals. The amplifier also offers a Bass Boost function, which can be activated by a switch located on the bottom of the device.

The design of the A8 is also designed to perfectly match the Aiyima T8 tube preamplifier, the latter being placed directly in the notch located on the top of the case.
