Product Summary
The Pro-Ject Pre Box S3 is a compact stereo preamplifier designed for customers who want one neat control centre for a modern hi-fi system. It is a strong option for customers who want to combine analogue, digital and wireless sources in one small component without losing the feel of a proper separates setup.
A big part of the appeal is the flexibility it offers. The Pre Box S3 includes MM phono, line-level analogue input, optical and coaxial digital inputs, HDMI eARC for TV sound and Bluetooth 5.0 with aptX HD, making it easy to build a system around vinyl, streaming devices, television audio and more. That makes it especially attractive for customers who want a compact preamp that can sit at the centre of a mixed modern system.
It is also designed to be useful beyond simple source switching. With a variable RCA output for your power amplifier, a fixed line output, a dedicated subwoofer output and a headphone output, the Pre Box S3 gives you a lot of real-world system flexibility in a very compact chassis. For customers wanting a small but very capable preamplifier with broad connectivity and genuine hi-fi usability, the Pre Box S3 is an excellent choice.
