A review by AVGUIDE on NAD's new digital amp

This is only a 2 channel amp and its weight is sill beefier than most AV Receivers using Class A/B x 7 channels.

It sounds pretty innovative. But if it's digital where is all the weight coming from?

That's a good question. I don't know

I'm reading it now but it looks like this has big and multiple power supplies:

.....Any noise or ripple on the supply rails is connected directly to the loudspeaker. Switching amplifiers thus require an extremely quiet supply. Nonetheless, many switching amplifiers skimp on the power supply in an effort to keep size, weight, and cost low. The M2 has a more substantial power supply than I’ve seen in any other amplifier with a switching output stage. Three separate supplies are used, one for each audio channel and one for the control circuitry and housekeeping.

It has to have multiple power supplies
