PSU Upgrades. Why?

I wonder how many people have added 'super clocks' to their digital gear and actually increased jitter & power supply noise / ground bounce due to improper grounding...

Yep it could well happen.

I think Simon answered the pertinent question some pages back:

Seems like you're missing the point.

You can't put £1000 worth of psu into a product that sells for £100. just like you can't put a engine from a £200,000 Ferrari inside a Fiat that sells for £5,000.

there's nothing broken in a £100 psu, that's just what you get for £100.

Its just that the £500 is better.

If you want better performance open your wallet for it.

The reason psu's are often the apparently cost limited part is that they are easier to substitute within a design. Any tit can plug in a new psu. Designing an amplifier to have a swappable output stage would be an altogether more difficult task and that's why it doesn't happen.


There nothing wrong with the performance of a cheap psu, it performs as a cheap psu is expected to perform. It's just that more expensive psu's can be better, much better.
