    REF1000M Monoblock Amplifier Features


    The Bel Canto Impedance Optimized Input Stage is a balanced high Common Mode Rejection, low output impedance driver that is critical to the amplifier's performance, ensuring that the refined dynamic qualities of the recording are preserved.

    Custom Power Input AC/DC Filter and Energy Storage
    Our custom AC/DC input filter and energy storage stage to allows the amp module to operate in a better controlled environment, providing lower noise operation and better dynamic signal handling, making the amplifier sound ‘bigger’ and conveying dynamic nuance more accurately.

    WBT NextGen Speaker Connectors
    The WBT NextGen connectors provide the best possible connection from the amplifier to the speaker cables. We choose them because they impart minimal sonic signature to the sound, remaining open and grain-free up throughout the audio frequency band.

    REF1000M Monoblock Amplifier Reviews

    Home Theater Review, Andrew Robinson, Feb 2010

    "In terms of sound there is little the REF 1000Ms can't do. They can power most any loudspeaker on the planet to insane volumes, 120dB peaks to be exact, and are extremely light on their feet, and are largely natural sounding with startling bass capabilities for a digital amplifier design. Where the REF 1000Ms excel is in their midrange and high frequency performance, which sounds more like a single ended triode amplifier in the sense of being incredibly nimble, open, airy and spacious versus syrupy, vague and recessed, which listeners often confuse for "warmth." In terms of soundstage width and depth the REF 1000M is among the best and the level of control and detail you'll hear is addictive…"
    Stereophile, Kalman Rubinson, July 2010

    "The Bel Canto REF1000M can be compared with the cream of the other amps I've had in my system… Because of this, I think I must keep the Bel Canto REF1000M as a reference amplifier—an easy decision even when based solely on its sound, but also: in my living room, none of the others can be so easily hidden in plain sight."
    Stereo Times, Russell Lichter/Bill Wells, April 2009

    “The REF1000M steps through a veil I didn't know was there; it creates an image of solidity, nuance and harmonic richness. Dynamic range is great, dynamic palette detailed.”
    “[T]hose looking for a superb musical amplifier, something with power, dynamics, control, finesse and musicality – I strongly suggest checking out the REF1000M.”
