Bryston SP3 Surround Sound Processor Review Highlights

This review covers the Bryston SP3, which is a 7.1 channel preamplifier / processor. The SP3 uses Class A discrete analog circuitry and does not use mass-market large-scale analog integrated circuits in the design of its output stages. Secrets of Home Theater and High Fidelity has published a series of articles on build quality and how component choices contribute to high performance design. Bryston is a great example of a company that takes component choice and design to heart. The SP3 does not strive to keep up with every mass-market product feature. Instead, it delivers on a singular goal of delivering outstanding sound quality for both two-channel stereo and multi-channel music and movies alike.

Dealing with the ever-changing HDMI landscape proved to be a big challenge for many of the high-end audio companies. Bryston took their time and developed the SP3 preamplifier / processor with a singular focus on audio quality. Their goal was to design an easy-to-use product that could perform in the world of high-resolution music and movie soundtracks, while still providing outstanding performance as an analog preamp. Let’s take a closer look at the SP3 and see just how Bryston went about tackling these goals.
