AUDIOPHONICS LPSU25 Alimentation Linéaire régulée Faible Bruit USB 220V vers 5V 2A 25VA - avis - Il y a 52 avis.

Now I'm a believer! :-) :-D
I did not measure the performance or ripple but I think that the sound quality improved: the piano sounds better.
I think I can hear the differences to the original (Allo) power supply even if I do not have high-end equipment.

I like the front and rear USB sockets and the surface finish.

I would have preferred a slightly harder power knob and a stronger feed-back but this is really not important and has something to do with the personal expectations.

The delivery to Germany was very fast.

My conclusion: excellent power supply.
Would I recommend it to my friends? - Yes!

perfect sound
It took long to decide which DAC I should buy, finally I ordered also the AUDIOPHONICS Linear Regulated Low Noise Power Supply USB 5V 3.5A 25VA and in just 5 minutes the setup was playing.
I am really surprised that a DAC can do so much in the sound on the same setup.
So the source is indeed the first important step.
At this price a big improvement over the HiFiberry DAC+ Pro

fait le job
je l'utilise pour le pasptouch digione
j’ai augmenter le voltage par la vis du potentiomètre a l’arrière

parfait
Effectivement il y a du changement dans le son ; grave plus tendu et aigu plus distingués
Il y a même une petite vis à l'arrière du produit qui permet de régler la tension
