NAD M66

The NAD M66 is a Masters series preamplifier, DAC and streamer, without a power amplifier. It is the component for somebody building a separates system rather than buying one box.

Where the M10 V3 puts everything in a single unit, the M66 concentrates on the source and control stages and leaves the amplification to a separate power amplifier of your choosing.

What Apple Home actually does with it

This is an AirPlay 2 device rather than a HomeKit accessory.

• It appears in the Home app as a speaker you can play to, and as an AirPlay target in Control Centre.
• You can put it in a room and group it with HomePods for synchronised multi-room audio.
• Siri can send music to it by room name.
• It can be the audio output in a scene or an automation.

Power, input selection and volume stay with the unit, its remote and its own app. The Home app does not control those.

Before you buy

Separates make sense when you want to choose the power amplifier to suit the speakers, or when you expect to upgrade one part at a time. They cost more in cables, shelf space and money.

Dirac Live room correction is included, which is one of the strongest arguments for putting a digital preamplifier in the chain at all.

BluOS provides multi-room across NAD, Bluesound and Cyrus, with AirPlay 2 alongside it.
