M28 Monoblock Amplifier
Still Waters Run Deep.
The Bricasti M28 monoblock amplifier is an exceptionally pure and precisely controlled reservoir of current. The expression of craft wrought in this deep pool effortlessly provides the massive current required to grab onto and control any speaker through the most demanding of musical passages. The sought after listening experience that is so elusive is immediately evident. The M28 is conservatively rated at 200 watts into an 8 ohm load. Ruler flat response and vanishing distortion, of course. Fast, articulate, distortion free low frequency performance, even at the speaker’s resonant peak, perhaps unanticipated.
Gain, Set, Match.
A balanced differential structure minimizes the stress across each of the M28 amplifier’s internal elements. Pairing the M28 with the balanced structure of the Bricasti M1 digital to analog converter forms a balanced differential signal flow from source to speaker. This unique pairing forms an optimized engineered system that announces a natural yet rarely heard sonic ease. For added flexibility the M28 offers 18 dB of stepped attenuated gain adjustment to enable proper level matching with any audio source or listening space. An RS232 link conveys status information for monitoring a number of system functions.
A harmony of concept and function, the M28 amplifier exhibits the precision and beauty of a thoroughly engineered system. The milled aluminum chassis is carved to exacting tolerances. Each electronic element mates to a purpose built location within the chassis. Thoughtful use of mass and passive ventilation assure the uniform distribution of heat and a cool touch under any load. Performance criteria is assured through both electronic and thermal design as well as an extensive analysis of each completed system.
John Newton, Recording Engineer and owner of Sound Mirror Mastering and Recording in Boston shares his insights into the Bricasti M28 monoblock amplifier in daily use. With more than 40 years of experience, Sound Mirror has produced recordings that are consistently acknowledged by the press, industry peers, and have racked up more than 80 GRAMMY nominations and awards.
«We at Soundmirror can’t thank you enough for your splendid development of the M28 and M15 amplifiers. Our experience with the first M28’s that we received was amazing. We had been using well known expensive amps in all of our listening rooms and were quite happy with them, until we heard your mono blocks. These are the first amplifiers that we’ve ever used that we couldn’t hear. It’s amazing to listen to classical music and not notice that there’s an amplifier working in the audio path. Power, clarity and frequency response are simply not an issue anymore. All of our clients who’ve worked in these listening rooms are equally amazed at the quality of the reproduction.
When the M15’s arrived they allowed us to economically equip another listening room with Bricasti amps by using the M15’s for the rear channels in each room thus freeing up M28’s for use in the front of the second room. We will equip our third room with Bricasti equipment when it is renovated late this year bringing our inventory of amps to 12 units!»
