Amp Box S3

Key Features

• Micro-sized footprint and casework for true flexibility in placement
• Improved S/N ratio with lower distortion for a more accurate performance

The Amp Box S3 is an efficient, yet powerful, compact power amplifier with true stereo hi-fi credibility. Thanks to its clever internal design it delivers a warm, inviting musical performance with the sonic characteristics of a tube amplifier.

The Amp Box S3 boasts a new PCB concept and sophisticated topology in order to achieve less distortion and a better signal to noise ratio. This audio-focused internal design is also highly efficient, with very little wasted energy. It also brings you a rich and musical sound with a touch of analogue warmth, inspired by the sonic traits of more costly valve amplifiers. By squeezing this clever technology into a deceptively small footprint, the amplifier is suited to a variety of applications.

Ideally suited to room sizes up-to 15m2, depending on the matched speakers, the Amp Box S3 can be useful for nearfield hi-fi systems, powering in-wall or in-ceiling speakers, or for enhancing the performance of existing hi-fi 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.

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 result is a purer musical signal that is true to the original recording, all presented in a spacious and comfortable sound stage.

Additional Features
• Advanced amplifier module ensures a quality in playback that belies its size
• Stereo inputs via RCA connectors
• Speaker sockets are isolated for purity of signal
• Banana/Spade/Pin/bare wire connectors offer the maximum ease of use
• Trigger input and output for using further amp Box S3 units in tandem and Pre Box pairing
• Aluminium metal casing and rubberised feet protect against vibration and interference
• On/Off toggle switch on the front fascia for simplicity in operation
• Handmade in Europe
• Available in Black and Silver finishes
