NAD Masters Series M10

STREAMING INTEGRATED AMPLIFIER

- JOHN ATKINSON

High-quality playback of digital audio is evolving in two opposed directions. One is where a smart wireless loudspeaker, like the KEF LSX 1 or DALI Callisto 6 C, 2 needs to be connected to a simple source of data. The other is where a smart amplifier takes the data from wherever it needs and sends it to a pair of dumb loudspeakers. NAD’s Masters Series M32 integrated amplifier ($4848 with its optional MDC DD-BluOS module), which I reviewed in May 2018, 3 is a great sounding example of the latter approach.

In the spring of 2019, NAD introduced the Masters Series M10 ($2749). At first I assumed that the M10 was a stripped-down, less-powerful version of the M32, but the new amplifier offers a unique set of features.

Like the M32, the M10 offers analog and digital inputs, but here the BluOS functionality, with its network, Wi-Fi, and Bluetooth connectivity, is included rather than optional. Yes, both amplifiers use a digital output stage, but while the M32 uses a “DirectDigital” amplifier that takes a digital signal as its input, the M10’s “Hybrid Digital” amplifier takes in an analog signal. The M10 also offers 50W less power than the >150W claimed for the M32. But NAD specifies that the M10 will offer “Dynamic Power”—ie, when the power demand is short-lived, as it would be with musical transients—of 160W into 8 ohms and 300W into 4 ohms.
