Default why sound best??

I build an power suppy and excange the diodes (1n5402) for 1n5822(fast diodes) and the sound is best (for my ears)....more bass and body sound.
What happened...why the sound is best?
Any scientific explication. no magic guru or other..
Wait

Hello tadiam1,

Search for information on harmonics and 'noise' created by conventional diodes when they charge power supply capacitors.

Some say that Schottky diodes are even better!

1N5822 are Schottky diodes .

tadiam1

What's your power supply dc voltage ? These seem to be just 40 volt diodes.

Yes. I should have checked. I answered by taking the information in the original post at at face value without checking, and did so in order to be quick and helpful after the first posted reply had been relatively unhelpful to tadiam1.

So the diodes should be at least 44V types. This one is 40 volts but then there must be higher margin so it's working.
