Ultra compact power amplifier - efficient & audiophile! 

A ultra high-efficiency Bi-Phase PWM(Pulse Wave Modulation) circuit with SMD parts incorporates 35 years of R&D and gives outstanding audio performance, while staying cool on the outside. 
It fulfills our demand for high resolution with superior micro dynamics and room-filling power. 
Sound quality is aimed to be as close as possible to Class A tube amplifiers with their liquid and lifelike presentation.

The Amp Box S Mono is micro-sized and therefore allows easy placement and can be switched on & off remotely via a trigger signal.

A 45cm power-on cable is supplied for this purpose. For Bi- or Tri-amplification use, the remote power-on signal can be relayed to further units.
