The BRAMA Monoblock Power Amplifier is a mono power amplifier from Vinnie Rossi, sharing the BRAMA platform's engineering philosophy with the brand's integrated amplifier and preamplifier, built for buyers wanting a dedicated separates-based power amplification solution.
Key specs that matter
Input impedance is 20k ohms, with an exceptionally low output impedance of 0.01 ohms. Output power is 300W into 8 ohms, doubling cleanly to 600W into 4 ohms. Gain is 22dBu. 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% with full global feedback. At 475 x 387 x 140mm and 20.4kg, the BRAMA Monoblock represents a substantial power amplifier commitment.
Sound and use context
Expect exceptional control reflecting the remarkably low 0.01-ohm output impedance - this low figure suggests outstanding grip over connected loudspeaker driver movement, delivering tight, well-controlled bass regardless of loudspeaker demands.
Pairing
The clean power doubling into 4 ohms and exceptionally low output impedance suit a wide range of loudspeaker impedances, and Vinnie Rossi's own BRAMA Preamplifier shares the platform's coherent engineering philosophy.
Alternatives
Vinnie Rossi's BRAMA G2 Integrated Amplifier offers a consolidated single-chassis alternative sharing the same core BRAMA platform, worth considering instead for buyers wanting a simpler system architecture.
