With the A23-M, PSI Audio delivers a compact 3-way monitor of the extra class and impresses with the generally new design and especially with its midrange driver. Developed from scratch, it convinces with exceptional values for sound pressure, linearity and distortion, while for adaptation to different production environments a plate detached from the rest of the housing allows the rotation of the midrange and tweeter driver - so the A23-M can be placed or laid as desired.

In addition, there is the so-called Adaptive Output Impedance (AOI), i.e. a monitoring of the diaphragm movements in relation to the input signal to ensure precise sound reproduction. Also worth mentioning is the Compensated Phase Response to ensure phase rigidity and avoid unwanted tonal changes in the source material. In general, each component works completely analog here. The same applies to the Class-G/H power amplifiers, which combine the advantages of Class-AB with lower distortion and increased efficiency.
