Bryston 3B (2.0) Stereo Power Amplifier

Bryston 3B Cubed 2.0 – compact stereo power amplifier with 200 watts per channel

The Bryston 3B Cubed 2.0 combines decades of amplifier tradition with modern circuitry and a particularly compact chassis. Its history dates back to 1973, when Chris Russell developed the PRO 3 prototype. Today, the 3B Cubed represents the consistent evolution of this concept and offers a powerful solution for high-end stereo systems with limited installation depth.

With 200 watts per channel at 8 ohms and up to 300 watts at 4 ohms, the 3B Cubed boasts ample power reserves. This makes the stereo amplifier suitable for a wide range of demanding loudspeakers and ensures impressive performance with both dynamic musical passages and finely detailed recordings. The sophisticated dual-mono design, with independent power supplies and dedicated transformers for each channel, contributes to stable and controlled sound reproduction.

The technical concept includes the patented Salomie circuit, which is used in the Bryston Cubed series amplifiers. Combined with the precise amplifier architecture, it enables detailed, neutral, and dynamic music reproduction. The gain can be set to either 23 dB or 29 dB, allowing for flexible adaptation to different preamplifiers and loudspeakers.

The shallow chassis depth is particularly practical. With a depth of only 27.3 cm (excluding front handles), the 3B Cubed can be integrated even where conventional power amplifiers reach their spatial limits. This makes it not only a powerful all-round amplifier, but also particularly suitable for hi-fi racks and installations with limited space.

For versatile system integration, balanced XLR and unbalanced RCA inputs are available. The fully convection-cooled design operates without a fan, ensuring exceptionally quiet operation. The robust housing, made of milled and anodized aluminum, underscores the high-quality and durable construction.

A soft-start microprocessor controls the power-on process and prevents unnecessary strain on the circuit. The DC trigger also allows for convenient integration of the amplifier into automated hi-fi systems. A standby power consumption of less than 500 mW contributes to efficient operation.

The 3B Cubed is also praised by specialist media for its combination of power, precision, and fine detail resolution. Among the highlights are its neutral yet pleasantly smooth reproduction and its confident control over various loudspeakers. The amplifier is particularly impressive in the treble range, delivering a precise and unobtrusive performance.

The Bryston 3B Cubed 2.0 is therefore an excellent choice for discerning music lovers seeking a powerful stereo power amplifier in a compact design. High-quality Bryston technology, independent power supply, low distortion, and flexible connectivity options make it a versatile component of high-end hi-fi systems.
