A chopper power supply still receives power from the mains in 50/60 Hz bursts (100/120 half-sines per second).
But even with a storage battery, the charger will have a 50/60Hz input.
One thing you say is correct: You, with no experience, don't know why the power supply uses a 50/60Hz transformer. Those of us who are experienced in the field have offered some insight. Yet you say we are wrong. Please explain how your lack of knowledge gives you this advantage.
And has nothing whatsoever to do with audio amplifiers?.
The supply to the processor won't be that clean either.
The advantages of a switchmode PSU for an audio amplifier are only these:
1) Smaller
2) Lighter
3) More efficient
4) Cheaper (possibly!)
Disadvantages are:
1) More complicated
2) More likely to fail (because of 1)
3) MUCH higher noise levels (which is why they aren't used).
If there were any audible advantages then they would be common place, as already suggested your entire premise is incorrect - you're overdriving a low quality amplifier and then complaining about it.
Are you sure you don't have a bad capacitor in your amplifiers power supply and thats why its doing what its doing? Try changing them out for something far larger and put in a bigger rectifiers as well. That will cure the ripple issue until the transformer looses from being overloaded kill it.
I don't recall you having ever mentioned what brand or model amplifier you have an issue with a so far either.
Well you're certainly not talking in general, as you're suggesting problems which don't exist, multi-kilowatt poweramps commonly use convemtional transformers and PSU's - yet they give enough power. I've never seen an amp that didn't (unless it was total crap), nor have I ever heard of any such claims apart from your's.
If you want to build a SMPSU for an amp you are of course perfectly free to do so, but your stated reasons are likely to end in severe disappointment.
High power car amplifiers use a switchmode voltage stepup converter and they don't produce the switching noise.
But since they don't have a 50Hz or 60Hz input then they don't produce 50Hz or 60Hz when they are clipping.
