Bryston Bi-200

Combining preamplifier and power amplifier in a single chassis without sacrificing performance: that’s the challenge the Canadian manufacturer set itself with the Bi-200. This model fully incorporates the circuits of the BP-19 preamplifier and the 3B Cubed power amplifier, two benchmark products in the catalogue, here assembled into a single unit. The result is a 200-watt-per-channel stereo integrated amplifier that directly inherits the know-how Bryston has accumulated over more than fifty years in professional and home amplification.

Two components, one single enclosure

The Bi-200 doesn’t just borrow the overall architecture of its separate predecessors: it uses their complete circuits. The preamplification section comes from the BP-19, itself derived from advances made during the development of the BR-20. The power stage, for its part, is exactly the same as that of the 3B Cubed, a stereo amplifier whose design dates back to the work of Chris Russell in 1973 and has evolved over successive generations. Only the mains power supply is shared between the two sections.

This approach fundamentally differs from that of traditional integrated amplifiers, where design compromises are often necessary to make the different functions coexist. Here, the two “components” coexist without mutual interference, connected internally by a balanced link that eliminates the need for external interconnect cables.

Dual-mono architecture and fully balanced signal path

The power stage operates in a dual-mono configuration: two strictly independent amplifiers, each with its own transformer and dedicated power supply, share the same chassis without electrical interaction. This separation ensures that a heavy load on one channel does not affect the performance of the other.

The signal path is fully balanced, from the XLR inputs to the output stages. This topology, traditionally reserved for professional studio equipment, improves rejection of electromagnetic interference, particularly useful when interconnect cables run several meters. The unbalanced RCA inputs are converted into a balanced signal as soon as they reach the preamplifier.

An analog volume control driven digitally

The Bi-200’s volume control deserves particular attention. It is an analog potentiometer with a continuously rotating encoder, whose position is controlled by a microprocessor. This hybrid solution preserves the integrity of the audio signal while offering precise adjustment in 0.5 dB steps, the finest ever offered on a Bryston integrated amplifier.

A small OLED screen on the front panel displays the level in decibels, although its readability from a distance remains limited. The display and LEDs can be set to several brightness levels, with programmable automatic switch-off. The LEDs themselves offer two color options: classic green or contemporary blue.

Remarkable distortion measurements

The published specifications attest to particularly meticulous engineering. The class A preamp section has a total harmonic distortion below 0.0006% across the 20 Hz – 20 kHz band. The complete signal path, including preamplification and amplification, maintains intermodulation distortion below 0.0005% and THD+N under 0.005% at full power.

The patented input stage uses a network of twelve active components that form an ultra-linear buffer, filtering out radio-frequency interference and disturbances coming from the power grid. The frequency response, nearly flat over the audible band with a deviation of ±0.05 dB between 20 Hz and 20 kHz, reflects this design rigor.

A headphone output derived from the BHA-1

The Bi-200 features the most capable headphone amplifier ever fitted to a Bryston product. Derived from the circuit of the BHA-1, the brand’s standalone reference model, this section offers a very low output impedance that allows it to drive the most demanding headphones effectively.

The output, accessible via a 6.35 mm jack on the front panel, benefits from a dedicated buffer that isolates it from the main power stages. The level of clarity and dynamic capability comes close to that of the BHA-1, providing a credible alternative to a separate headphone amplifier.

Connectivity and system integration

With its six analog inputs, including four RCA and two balanced XLR, the Bi-200 accommodates a wide range of sources. The preamp outputs, available in both RCA and XLR, are offered in fixed or variable versions depending on the intended use: bi-amping, recording, or driving an active subwoofer.

Home automation integration is handled via a bidirectional RS232 interface, complemented by Ethernet and USB connections for remote control. A DC Trigger allows power-on to be synchronized with other devices. The BR-4 infrared remote control, supplied as standard, also operates Bryston digital players.

Passive cooling and construction

The Bi-200 operates in class AB and dissipates its heat solely through natural convection, with no fan. The absence of moving parts contributes to silent operation and long-term reliability. The machined aluminum chassis plays both a structural and thermal role, while minimizing resonances.

The Soft-Start progressive startup system avoids sudden inrush currents at power-on, protecting the electrical installation and internal components. Standby power consumption remains below 0.5 watts, a particularly low figure for a device of this power.
