The power supply for an amplifier is the source impedance/energy of the amp components you place after it . Low value / ratings ? lack of punch, lack of ability to supply that energy required when needed.
This is also true for the output stages of the amp.
Low switcher count/rating = weak amp, game over.
You'll find that the higher end amps have more switchers, providing lower resistance, giving the ability to switch higher currents. Mosfets de-rate themselves when warm/hot and you end up with maybe 40 to 60% of original rating. This is why alot of amps die as their supplies cant cope when hot.

The amps PCB board layout is as critical or more critical than just using good parts.
A good analogy is to take two identical car using identical equipment.
Then have it installed by two different install shop. I can guarrantee you 1000% that they will sound different.
Why? basically, the physical position(s) of the parts on the PBC will determine one of the main outcome of how they will sound.
