    I usually wouldn’t judge

    a $6000 product against

    one costing more than

    $50k, but the M2’s

    outstanding performance

    in many areas invited

    the comparison.

    What reviewers sayProducts supported by Qualcomm® DDFA™ Amplifier Technology

    Qualcomm DDFA is a product of Qualcomm Technologies, Inc. and/or its subsidiaries.

    I admit to having been a little suspicious

    at first of the PCM-to-PWM approach

    that NAD has taken in the M51. That

    was before I'd had a chance to live

    with it for a couple months. …the

    NAD M51 succeeds with a wonderfully

    detailed and revealing sound best

    described as honest, with a friendly

    smile. And it was a pleasure to listen to.

    — Stereophile.com,

    NAD M51

    Every album (…) sounded like

    real flesh and blood musicians,

    and the amazingly low noise

    floor was certainly a factor.

    I listened to a lot of the

    Blue Note 192 Khz remasters

    and the tonality of these

    vintage recordings was

    simply breath-taking.

    As speakers get smaller, amplification matters more*above statistics based on findings from Qualcomm State of Play report 2018

    Demand for portable

    and smaller form factors

    Demand for premium

    audio across all tiers

    Almost half of participants in our 2018 surveywould like to use their smart speaker “on-the-go”
