New Linear Power supply upgrade for DMP A-6

One of my computers does it. Sorry, its a true thing. Here we call it "fiepen" which is a almost ultra sonic sound.
I don't expect that the powersupply in the A6 will do it because it is obviously potted.
Nevertheless the condensatores can still age. And then you can replace the whole board. Whats not to like?

 

If the extremely highly unlikely event that your power supply imitates a helicopter simply send it back to Eversolo.
This stupid notion that ‘boutique’ power supplies can improve the SQ of well designed components has to end.

You should maybe not make fun of the wording of people who are not native english speakers.

For you I post this very interesting commentary I found on Youtube.
(5) Audiophile Linear Power Supplies - Do they improve the sound? - YouTube

 

I wouldn’t watch videos presented by the technically unaware whose sole purpose is monetisation.

Actually, they are not only "slightly" higher quality. They are "extremely-low-noise" ones...

 

IME electrolytic capacitors can and do eventually deteriorate or fail. It's just how they make them these days. Yes, there are more reliable and higher quality capacitors that could be used but in these days of cutting costs manufacturers invariably choose cheaper alternatives with a typical MTBF of as little as 1000 hours. Over the years I've repaired more SMPS caused by faulty low ESR capacitors that I care to remember. Often failures are made worse by poor PCB layouts where some idiot designer has an electrolytic or three located way too close to a heatsink and it ends up drying out the electrolyte in the capacitor thus lowering the capacitance, raising the ESR and even sometimes venting. BTW, electrolytic capacitors in LPSU fail as well.
