The Amp Box S3 is a space-saving, yet robust hi-fi stereo power amplifier, boasting an efficient yet powerful design that results in a warm, inviting sound that emulates the sonic characteristics of tube amplifiers.
The Amp Box S3 is specially crafted to minimize distortion and maximize the signal-to-noise ratio with a cutting-edge PCB concept and refined topology. This energy-efficient construction provides a rich, musical sound with a hint of analog warmth akin to high-end valve amplifiers. It also packs this advanced technology into a space-saving design, making it ideal for a variety of applications.
This small-scale amplifier is designed for rooms up to 15m2 in area, depending on the associate speaker setup. It can strengthen nearfield hi-fi systems, drive in-wall or in-ceiling speakers, or upgrade existing hi-fi and home theater systems with one stereo RCA input, a jack output, and trigger connections. Additionally, multiple amplifiers can be incorporated into 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.
