SMPS - PS Audio
https://www.psaudio.com/pauls-posts/smps/
A SMPS is a linear power supply only it doesn’t have a big power transformer like what we think of when we mention a linear supply. Audiophile wisdom suggests that linear supplies are better, especially in power amplifiers, than SMPS. If you try and nail down why this thought prevails the arguments quickly fall by the wayside because, well, we don’t actually …

Watts and for all amps to deliver their power at once, the power supply would have to match plus supply power to the amplifier loses. If, how ever, each amp is tested separately, which is likely the case, then the wimpy power supply may do the job and may be adequate for music where the power is never continuous.
