Aiyima D03 is an FDA (Full Digital Amplifier) amplifier that offers good power reserves as well as accurate and transparent sound reproduction. It is indeed capable of delivering at least 2x120W under a 4Ω load (THD+N 1%) with high efficiency, thanks to the TI TAS5624A amplifier chip.
In addition, it has a particularly comprehensive range of connectivity options: USB-B, optical Toslink, coaxial, stereo RCA (ADC PCM1808) as inputs, as well as Bluetooth 5.0 reception. Practical, this new amplifier allows you to remotely receive music from your smartphone, taking advantage of the aptX and aptX-HD high-definition Bluetooth codecs. On the output side there are, of course, terminals for the speakers, as well as an output for the active subwoofer, on an RCA connector.
