The BRAMA G2 Integrated Amplifier is a comprehensive integrated amplifier from Vinnie Rossi, an American manufacturer known for considered, modular electronics design. The BRAMA G2 brings substantial connectivity and flexible gain settings to a complete integrated chassis.
Key specs that matter
Five balanced inputs are provided, with input impedance at 20k ohms and output impedance at 100 ohms. Output power is 2 x 200W into 8 ohms, doubling cleanly to 2 x 400W into 4 ohms - a textbook power doubling indicating a robust, well-regulated power supply. Gain is switchable across three steps (22, 28, 34dB). Frequency response spans a wide 5Hz to 100,000Hz within plus-or-minus 3dB. Signal-to-noise ratio reaches 100dB, with total harmonic distortion plus noise at 0.1%. At 475 x 406 x 140mm and 22.7kg, the BRAMA G2 represents a substantial integrated amplifier commitment.
Sound and use context
Expect substantial power delivery with genuine flexibility from the three-step switchable gain, letting a listener match the amplifier's sensitivity to a specific source and downstream loudspeaker combination.
Pairing
The clean power doubling into 4 ohms and switchable gain settings suit a wide range of loudspeaker sensitivities and source output levels, easing system matching considerably.
Alternatives
Vinnie Rossi's own BRAMA Preamplifier and BRAMA Monoblock Power Amplifier offer separates-based alternatives sharing the same modular BRAMA platform, worth considering instead for buyers wanting to build a system incrementally.
