The BR-20 is a comprehensive preamplifier from Bryston, built with balanced two-plus-two input-output connectivity and an exceptionally low distortion figure. The BR-20 brings Bryston's considered engineering to dedicated line-level signal control.
Key specs that matter
Two balanced and two single-ended inputs are provided, with two balanced outputs. Frequency response spans 20Hz to 20,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is 110dB unweighted, with total harmonic distortion plus noise under an exceptionally low 0.0006% - a remarkable figure indicating exceptionally clean signal handling.
Sound and use context
Expect exceptionally clean, transparent signal handling reflecting the exceptionally low 0.0006% distortion figure, consistent with Bryston's broader precision-engineered philosophy backed by the brand's storied long warranty.
Pairing
Bryston's own power amplifier catalogue, including the 7B Cubed and 14B Cubed, offers natural, brand-coherent pairings for a coherently voiced, entirely Bryston-based system.
Alternatives
Other manufacturers' comparable precision preamplifiers offer alternatives for buyers wanting to compare measured performance at a similar price point.
