Judges’ Citation: One of the few true digital Class-D amplifiers on sale, the sophisticated M32 integrated model uses NAD’s ‘DirectDigital’ technology to deliver a claimed 180W per channel. Combining pre- and power amplifier functions into a single amplifying stage, it’s both technically innovative and highly versatile. Furthermore, an optional BluOS module opens the doors to streaming and networked music playback, making it highly future-proof. Confident and assured, this amplifier sounds open, detailed and expansive—giving a panoramic feel to every piece of music it plays. With its touchscreen display and app control, it’s a breeze to use too, and the robust aluminium casework is as substantial as its sound.
