The 7B Cubed is a powerful monoblock power amplifier from Bryston, built with substantial output power and an exceptional signal-to-noise figure backed by Bryston's storied warranty. The 7B Cubed brings Bryston's considered engineering to dedicated monoblock power amplification.

Key specs that matter

Input impedance is 5,000 ohms balanced or 7,500 ohms single-ended. Output power is a substantial 600W into 8 ohms, rising to a staggering 900W into 4 ohms. Frequency response extends down to 1Hz and up to a wide 100,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is an exceptional 119dB via XLR or 117dB via RCA. Total harmonic distortion plus noise is under 0.005% at 100% global feedback. At 480 x 160 x 411mm and 27kg, the 7B Cubed represents a serious monoblock commitment reflecting Bryston's considered Canadian engineering standards.

Sound and use context

Expect extraordinary dynamic authority reflecting the staggering 900W-into-4-ohms output combined with the exceptional over-119dB signal-to-noise figure, consistent with Bryston's broader precision-engineered philosophy.

Pairing

As a monoblock two units are needed for a stereo pair, and Bryston's own preamplifier catalogue, including the BR-20, offers natural, brand-coherent pairings.

Alternatives

Bryston's own 14B Cubed offers a stereo alternative with matching output power within the same broader catalogue.
