On the paper, it is better to use separated SMPS.
In real world, my experience tells-me the contrary. And i tend to prefer one SMPS for the two stereo channels as well, instead of the hype two mono blocs configuration.

The reason is that the supplied voltage tend to collapse a little during transients. even with the best regulated SMPS.
In monoblocs configuration this affect only one channel, if the transient is only on this one: your stereo image will move during this transient. An unique SMPS will keep the stero image stable, because the overall gain will stay equal between the two channels. So for multi-amplification of active speakers, in regard to bandwidth coherency. On that point of view, passive filtering gives more natural results for the same reason. But active present other advantages.
Chose your poison.

Depends on the load.
Obviously a single 600W supply will be a bottleneck if two NC400s (try to) dish out 400W or, even worse, 600W each (@4R and 2R respectively, 1% THD).

Yes I suppose. I have difficulty imagining that a 400w amp would be power limited in a home environment though (and I listen loud).

some have far less than 1% efficient speakers, hence the discussion about bridging the ncore some pages back in this tread

Haha, I had two of those running at 4 30cm Dynaudio woofers per side ( 2 Ohm):

Just curious, knowing other Crown amps capability in the low end:
do you feel the ncore have as much "grip" and authority driving direct radiator woofers as Crown?

Really?

As long as the amplifiers are not so close to their maximum output that they are clipping, the output will be independent of the power supply voltage (the supply ripple rejection of the nc400 is specified as at least 75 dB, the "near-static" power supply voltage variation rejection is probably much higher still.

75 dB means a 10% in the supply voltage will cause an output variation of 0.002% of full scale...

Can't tell, it is more than 10 years ago I owned this Dynaudio M4 4 way active studio monitor ( I build it myself). But one thing I can tell, those Crowns where awesome....... 32 output devices and 41 Kg ( monoblock)
