THE PRO-JECT AMP BOX S3 IS A NEW VERY COMPACT STEREO POWER AMPLIFIER

Pro-Ject’s new micro stereo power amplifier the Pro-Ject Amp Box S3 costs under £270 and is super compact.

Pro-Ject says that the Amp Box S3 is an “efficient, yet powerful, compact power amplifier”.

The Pro-Ject Amp Box S3 has a new PCB concept and sophisticated topology in order to achieve lower distortion and a better signal to noise ratio. Pro-Ject says that this audio-focused internal design is also efficient, with very little wasted energy. By squeezing this technology into a deceptively small footprint, the amplifier is suited to a variety of applications.

BI AND TRI-AMPING

Ideally suited to room sizes up to 15m2, depending on the matched speakers, the Amp Box S3 can be useful for nearfield HiFi systems, powering in-wall or in-ceiling speakers, or enhancing the performance of existing HiFi and home cinema systems. With one stereo RCA input, a jack output, and trigger connections, it’s also possible to stack multiple amplifiers for bi- or tri-amplified systems.

CASEWORK

Sitting on four rubberised feet and contained within a sturdy metal casework that boasts a clean, minimalist elegance for when it’s on show, the Amp Box S3 is designed to protect itself from electronic interference and vibration.

The new Amp Box S3 is designed and produced in Europe and is available in a black and a silver finish.
