NAD Amplifier Design

I'm doing a deep dive into NAD's amplifier design and how they rate the output power. They rate their average output at the same power for both 4 and 8 ohm impedance loads, but dynamic power progressively increases at the load impedance drops as expected. I understand the marketing benefit of offering a constant power output and low distortion with headroom regardless of speaker impedance, but is there more to the amplifier design, or is this just "NAD's thing"? I read that there is also voltage switching as need to produce more power for a high draw, but I assume it's just a well designed class A/B circuit?
