Power amplifiers stereo — Bryston BD-225

The BD-225 is a stereo power amplifier from Bryston, built with solid measured performance and an extraordinarily wide bandwidth. The BD-225 brings Bryston's considered engineering to a two-channel power amplification format.

Key specs that matter

Input sensitivity is 1,500mV. Output power is 225W into 8 ohms, doubling cleanly to 450W into 4 ohms - a textbook power doubling indicating a robust, well-regulated power supply. Gain is 29dBu. Frequency response spans an extraordinary 1Hz to 45,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is 103dB. At 451 x 133 x 425mm and 24kg, the BD-225 represents a substantial stereo amplifier commitment.

Sound and use context

Expect clean, powerful amplification reflecting the solid 103dB signal-to-noise figure combined with the clean power doubling into 4 ohms, suggesting genuine authority across a wide range of loudspeaker impedances.

Pairing

The clean power doubling into 4 ohms suits a wide range of loudspeaker impedances, and Bryston's own BP-2 MM/MC phono stage shares the brand's coherent engineering philosophy.

Alternatives

Bryston's own BD-325 sits above this model with considerably greater output, worth comparing directly to find the right Bryston amplifier tier.
