M28 Mono

About the M28 Mono

The Bricasti Design M28 monoblock amplifier is a reference-class analog power amplifier known for its exceptionally pure and precisely controlled current delivery. It is conservatively rated at 200 watts into an 8-ohm load, 400 watts into 4 ohms, and 800 watts into 2 ohms, making it suitable for demanding high-fidelity applications. The amplifier features a fully differential balanced topology with balanced XLR inputs (200k ohm impedance) and unbalanced RCA inputs (100k ohm impedance). A unique input trim control allows attenuation in 6 dB steps up to 18 dB to better match preamp outputs or drive directly from a DAC, enhancing flexibility and performance. The M28 offers outstanding audio performance with total harmonic distortion less than 0.005% from 20 Hz to 20 kHz at full rated power, a frequency response of 10 Hz to 150 kHz within 0.5 dB, a gain of 27 dB, and a signal-to-noise ratio greater than 85 dB at full power. The amplifier weighs approximately 80-85 lbs and measures 11.9" wide by 13.8" high by 17.8" deep. It complies with EMC and RoHS standards, ensuring quality and safety. The M28 is designed as a true reference amplifier for audiophiles seeking uncompromising sound quality and power delivery.
