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.
Read Amir’s reviews/measurements at ASR , no adverts no posting for financial gain.

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.

 

Has anyone tried the

Akiko Audio Speaker Improver
Review said it reduces noise for passive speaker, like how airplane noise is reduced so you hear more of the music (I love my Bose noise cancelling headphones for airplanes).

 

Snake oil bullshit.

@FunnyChap : I asked you this more times. When you go on your knees to your speakers and open up the volume of your amp to max without playing any music and you here nothing as absolute silence...
what noise will you reduce??? But, believe in it and buy it. Then you have another stupid thing in your audiofool collection. And please! Do a review and post it here.
Life is too serious without freaks like you. Thank you!

 

I have several Akiko devices, though not those ones, and I have found them to work very well. Ignore those who haven’t tried them!

 

One born every minute.

'Utilizes crystal patterns and paramagnetic piezoelectric properties of natural raw materials, like minerals and gold, to reduce high-frequency noise in the audio signal fed into passive speakers'

 

If you are a strong believer, it will happen!

 

:-D
This must definitely go to the Extreme Snake Oil thread on ASR... do you agree @Purité Audio ...? ;-)

 

Just ordered LPSU from aliexpress, seems pretty much same as Beatechnik, but with different transformer and cheaper, seller confirmed that it is LHY brand.

In my expiernce PSU type affects sound quite a lot, even when manufacturer claims otherwise. For example my RME Adi 2 Dac FS with LPSU sounds much cleaner, than with stock SMPS, even my wife detects it in DBT 10 out 10.

 

For this to be really valid your wife had to have been in the kitchen.

That's how you are testing your gear?

 

If you understood what the measurements mean then you would realise that a seperate power supply cannot make the slightest difference. Stop looking at moronic you tubers and start reading.
Keith

 

I beg your pardon, but my ears is the only thing I trust.

 

Ears really aren’t very trustworthy.
If you really want to compare buy another Eversolo unit and compare the two level matched and unsighted.
But if you understood the measurements you would know that a separate power supply cannot improve the sound quality.
