Yes real value for the money.
They should add a trim to reduce brightness of the 7-segment display. Its a bit bright.
Their domestic retail price in China Taobao shop is around 360-400 RMB/pc, even higher than the net price on Aliexpress! I am thinking about how to place order on their Aliexpress shop and ship to China.
don’t have a CE mark. but you can order from China

you can buy a lot of this LPS from aliexpress.
I have been impressed by my dual LPS from a AE seller called Sengterbelle. It has an R core transformer and is there in single and in dual

When do you think a linear power supply is needed?
I think my power grid is pretty stable. On my rPi I use only one USB port for an external HDD (which however has its own dedicated power supply), the network is wired and I use an Allo Boss I2s card connected via coaxial cable to my amplifier.
Do you think a linear power supply can bring me some improvements?

in 99% of the cases a LPS provide a better sound for sure.

Got the unit today. I ordered it after reading your comments and I’m really glad I did.
I have the distinct feeling of an improvement. More solid and detailed soundstage.
Thank you very much for recommending it!
I have a question: I didn’t change the output voltage, I left it as it was and it shows 5.04. Do I have to change it or do I leave it like this for my Rpi3b +?
I would turn the output voltage a little bit higher, to approx… 5.15V. if you have an accurate voltage meter, you can even swing it a bit higher. Max 5.25V
Sorry for my ignorance on the subject, but what is the impact of using more or less voltage in terms of audio performance?
it gives you a bigger margin on voltage drop due to connected USB devices or GPIO pins. If for whatever reason the voltage drops below 4.85 V, the rPi starts to become unstable.
Hello, I am currently using this power supply exclusively to power my Raspberry Pi 3b+ where I have installed Volumio. However, I am planning to purchase a Topping D50III DAC and I’d like to ask if you think I can use the other 5V USB port of the power supply for that and so power both the DAC and the Raspberry Pi without any issues.
Thanks in advance.
I am powering both an rpi5 and Topping E50 from the same supply. So far (besides it’s gets warm) no issues found.

To confirm for those interested: for the past three weeks I have had my new Topping D50 III dac which I connected to this linear power supply (where the Raspberry Pi 3b+ with Volumio is also connected).
Aside from the high temperatures reached by the power supply (you can cook an egg with it) which I think also depends on the high outside temperatures these days, everything works and sounds great!

I guess you mean this one?
I have 2.
One operates at normal temp, about 40deg.
The 2nd is really really hot.
Strange I’ve opened them both, exactly the same layout.
Left is de PSU aka Egg boiler aka heater and right is the one with normal temp.

Yes, I mean that one.

Now I am curious if yours also contains the black grey capacitors as in the left unit. This one (Hot) is the newest unit.
The big blue coils(?) also have different output voltages, one is 9v, the other 7v.
