    DESCRIPTION +

    Meridian's Hi-Res Audio amplifier, bridgeable to >1.5KW, is also available as a dedicated rack-mount variant and incorporates a totally new design based upon extensive research. Tremendously powerful with an incredibly low noise floor, the Meridian 857 represents a step change in amplifier design

    FEATURES +

    Introducing the future of Hi-Res performance.

    • Effortless power delivery of 500W per channel into four ohms and bridgeable to >1.5kW mono into four ohms.
    • Low-feedback construction provides ultra-low distortion, ensuring an unparalleled level of clarity and transparency across the audible range.
    • Balanced and unbalanced inputs are provided, with unbalanced inputs converted to balanced before they enter the amplifier using Meridian’s proprietary ‘Superbal’ technology.
    • Designed to operate in thermally hostile environments, including in-rack when the dedicated Meridian 857 rack mount variant is specified.
    • When in standby mode, a standing voltage is maintained, meaning that optimum performance can be achieved almost immediately after switching the Meridian 857 on.
