Project Amp Box DS

The Amp Box DS is the ProJect Box Designs' midrange audiophile quality power amplifier. This unit provides robust and powerful stereo amplification, capable of filling and exciting even the most demanding of loudspeakers. The output sound of the Amp Box DS is described as being 'warm, powerful and full of colour', retaining the smooth sound one would experience when listening to analogue music, as opposed to the sometimes harsher response of digital music.

The circuitry within the Amp Box DS uses an ultra high-efficiency Bi-Phase PWM (Pulse Wave Modulation) technology, consisting of SMD parts. This allows the amplifier to perform at an outstanding level while the unit retains cool on the outside. The Amp Box DS has been designed to retain a life-like and liquid representation, through a warm medium that one would expect to experience from Class A valve amplifiers.
