This is verbatim out of my M-400 Owner's Manual
The M-400 is remarkably efficient: considerably more efficinet than conventional amplifiers. Its power supply can momentarily "assign" power as required: Unused power from one channel is available to the other by as much as 300 watts.
But I don't necessarily think this is the sole province of Magnetic Field amplifiers. Maybe some EE can step in here and help us out, but it seems to me that any rail switching stereo amp that shares a power supply should be able to do the same thing if the output devices can handle more current. With only one channel driven, the power supply can still deliver most of its power to that channel, with only the power required for the low rail on the other channel subtracted. An M-400 has three rails. An M-500 has only two, so it should be able to deliver proportionately less.
It should sound like it isn't there!
There is a difference between hearing and listening...
