Vinnie Rossi Brama Power Amplifier

With just three precision-matched lateral MOSFETs per rail, our output stage commands a robust 600 watts per channel into 4 ohms and 1200 watts into 2 ohms. This purist Class AB design unfolds every subtle detail and dynamic sweep with absolute grace and unwavering conviction, no matter the demands your loudspeakers place on it.

Effortless Power: The Brama Amplifier Stage

What makes Brama’s power amplifier stage unique? The power amplifier stages in the Brama Integrated Amplifier and Monoblock Power Amplifiers are meticulously engineered two-PCB stacks. The upper PCB carries the fully balanced input and driver stages, while the lower PCB houses the Class AB MOSFET output stage. The output devices themselves are mounted directly to Brama’s solid-body aluminum chassis, transforming the entire structure into an efficient, silent heatsink. This compact, elegant architecture preserves signal purity while ensuring stability and effortless power delivery.

Why use a stacked design? Because it keeps the signal and power paths exceptionally short. It also isolates the more delicate input and driver stage circuitry from the power output stage. Components are mounted on both sides of each PCB, eliminating the need for long PCB traces and internal cable runs. The result is lower noise, tighter control, and a level of transparency that simply isn’t achievable with more sprawling layouts. In Brama, this remarkable layout approach directly serves the purity of the music.

Why use so few output MOSFETs compared to other amplifiers? Many amplifiers rely on a large array of inexpensive transistors to achieve high output power. Brama takes a different approach. We use a small number of carefully computer-matched lateral MOSFETs – two per rail in the Integrated, three per rail in the Monoblock. By minimizing the number of output devices, we reduce congestion, preserve microdetail, and maintain a holographic, natural presentation.

How much power does Brama deliver? The Brama Integrated Amplifier delivers 200W RMS into 8 ohms and 400W RMS into 4 ohms. The Brama Monoblock Power Amplifier takes this further: 300W RMS into 8 ohms, 600W RMS into 4 ohms, and an astonishing 1200W RMS into 2 ohms. With such reserves, Brama drives even the most demanding loudspeakers with absolute authority – yet always with finesse.

How did VinnieRossi® design it for the highest reliability? Brama continuously monitors its own operating conditions. DC offset is servo-controlled at the input stage to maintain 0V at the speaker outputs. Temperature and output current are monitored in real time, with intelligent protection circuitry ensuring safe shutdown in the unlikely event of a fault. What does this all mean for the listener? It means power without harshness, control without constraint, and scale without sacrificing intimacy. Brama’s amplifier stage doesn’t just deliver wattage – it delivers music with flow, texture, and presence. From the softest whisper to the most commanding crescendo, every note emerges with authority, detail, and grace.

Power Perfected from the Ground Up

Why don’t Brama components use traditional power supplies? Conventional toroidal transformers, common even in very high-end audio components, have limitations. Under load they introduce noise throughout the audio band and “choke” musical dynamics because of their inductive properties (a consequence of Lenz’s Law). Their output voltage also sags when your AC mains fluctuate or when there are strong demands in the music. In short, they can get in the way of music’s natural flow.

What does Vinnie Rossi® do differently? Brama’s power supplies are custom-designed from the ground up, exclusively for high-end audio. Every model features a precision-engineered switch-mode power supply (SMPS) with active power factor correction (PFC). By drawing power cleanly from the wall, PFC ensures the supply itself never introduces noise or interferes with other components. The result is rock-solid voltage, ultra-low noise, and lightning-fast response.

How does this benefit music? Because Brama’s power supplies respond instantly – without the lag or sag of conventional designs – music flows effortlessly, with every subtle nuance intact, regardless of fluctuations in the incoming AC line. The noise floor remains far outside the audio band, so every note emerges from a foundation of pure silence. From the quietest whisper to a thunderous crescendo, dynamics are preserved with ease and authority, even when driving the most demanding loudspeakers. Music isn’t just played – it is experienced in its full emotional and sonic depth.

How is the design executed? Every Brama power supply is fully enclosed in its own CNC-machined chamber within the solid aluminum chassis, completely isolated from the audio circuitry. Internal wiring is kept to just a few centimeters, minimizing interference. In the linestage sections, patented Belleson linear superregulators provide an exceptionally low noise floor, while the power amplifiers feature dedicated 2400W peak supplies for effortless headroom and control. The result is a system where every element is meticulously crafted to let the music breathe and flow effortlessly.

Why isn’t this approach to power supply design more widely adopted? Designing a true audio-grade power supply from the ground up is expensive and time consuming. Manufacturing at this level is far costlier than producing a conventional supply of comparable output. Coupled with the prevalence of inexpensive switching supplies in consumer electronics, many companies hesitate to take on the challenge of educating audiophiles that not all SMPS are created equal. There’s also the long-standing belief in high-end audio that “bigger and heavier must be better,” favoring bulky traditional transformers. Brama challenges that assumption – just one listening session with your favorite music, and you’ll be convinced.
