The Bryston 2.5B SST³ is a precision power amplifier designed for exceptionally low distortion, stability and long-term reliability. It features an active low-distortion input buffer with both balanced and unbalanced inputs, plus selectable 23dB or 29dB gain for flexible system matching.
All voltage-gain stages use regulated power supplies, while each channel has an independent supply for improved separation and consistent performance.
The amplifier is housed in a fully aluminium, convection-cooled chassis with no fans or moving parts, ensuring silent operation and dependable long-term performance.
A rear-panel bridging switch converts the amplifier to a single 360W mono channel when additional power is required.
