M28 MONOBLOCK POWER AMPLIFIER
M28 MONOBLOCK POWER AMPLIFIER
Dual mono design: Each monoblock amplifier is fully isolated, with a dedicated power supply and signal path per channel for exceptional channel separation and clarity
High output power: Delivers substantial current to drive even the most demanding speakers with precision and control at any volume level
Advanced power supply: Dual high-current linear power supplies ensure consistent and efficient performance
Internally balanced: Fully balanced signal path maximizes the benefits of dual-differential design while reducing noise and distortion
Finish available in Classic black, Argento silver, and Platinum
The Bricasti M28 Monoblock amplifier is an exceptionally pure and precisely controlled current source. Expertly crafted, it delivers the substantial current required to drive and control any loudspeaker, even during the most demanding musical passages. The elusive listening experience so many seek becomes immediately apparent.
GAIN, SET,
MATCH
A balanced differential structure minimizes stress across the M28 amplifier’s internal elements. When paired with the balanced architecture of the Bricasti M1 digital-to-analog converter, the M28 creates a fully balanced differential signal flow from source to speaker. This pairing results in an optimized, engineered system that delivers a natural yet rarely heard sonic ease. The M28 also offers 18 dB of stepped attenuated gain adjustment for added flexibility, allowing precise level matching with any audio source or listening environment. An RS232 link provides status information for monitoring a range of system functions.
BEAUTIFULLY
BUILT
A harmony of concept and function, the M28 amplifier reflects the precision and elegance of a thoroughly engineered system. The milled aluminum chassis is machined to exacting tolerances, with each electronic element placed in a purpose-built location to ensure optimal performance and integration.
AMPLIFIED
PERFORMANCE
Thoughtful use of mass and passive ventilation ensures uniform heat distribution and a cool-touch chassis under any load. Performance is guaranteed through careful electronic and thermal design, along with extensive analysis of each completed system. The M28 is conservatively rated at 200 watts into an 8-ohm load. Expect ruler-flat frequency response, vanishing distortion, and fast, articulate low-frequency performance—even at the speaker’s resonant peak, where such control may be unexpected.
FEATURES
FULLY DIFFERENTIAL
TECHNOLOGY
The M28 monoblock amplifier features a fully balanced, dual mono design with separate amplifiers for each channel, delivering exceptional signal fidelity. Preventing negative signals from contacting ground reduces crosstalk, noise, and interference, improving the signal-to-noise ratio for a more natural, lifelike sound at any volume.
Handcrafted in the USA
All of our products are crafted in the old world tradition, in a classic brick mill building in Massachusetts USA by a team of individuals dedicated to excellence.
