R core rocks, i been using this for pi2aes mercury. Clean pure night and day vs switched maxell 12v that it came with smps .

Hello everyone, I have 5v, 12v and 15v. I am very happy with how it works. Thankyou so much for the videos.

Thank you! That's quite a collection :)

These LPS in UK from Sound Hi fi are 400 500 GBP... MINE cost 42GBP

Ein Netzteil, was auf der Front keinen Netzschalter hat - ist unpraktisch! Soll man dann im Regal mit der Hand nach hinten greifen und nach dem Schalter suchen ? Dieser Vertrieb hat auch Netzteile mit Schalter vorne. Habe davon bereits 3 Stück (auch mit 2 Stromausgängen auf der Rückseite). Händler liefert zuverläßig in Deutschland per Hermes, bisher kein Zoll drauf gewesen.

Yes that's a valid point, it's not the most convenient to reach, but it looks better witch switch on the back and clean front plate. People with nice equipment racks won't be bothered:) I'm personally using Tuya controlled switches before my EMI filtered power strips so I'm turning on all of needed equipment with one touch of remote Tuya button - no reaching for power switches at all!

Could You give a link too this on Alliexpress ? Pozdrawiam. Michal

Jasne, updated the desc with the link to the one I got. Cheers!

is there any advantage of a R-core vs ring transformer

@k4syx

Ай бұрын

Rcore transformers have more uniform electromagnetic flow so they should be more efficient and create more stable output. Is this audible? Will see about that as I have one more on the way that seems to have exactly the same build and different trafo (standard toroidal one)

No, no fuse. Good point. I'll have to diy something.

None at all. Can be diy with ready made socket with fuse, but the point is it should be there

I notice a screw near the iec. I’m not an electrical engineer and I never open my equipment. But, this may be where a fuse is.

Holy shit, those bare wires going to the main power switch. Now thats awful. Other than that i am fine with the construction. I am not into HIFI i dont know how i got here.

This is linear power supply so if replaces your regular wall wart impulse power supply with clean, stable DC supply. It can be used for your DAC, HTPC, external clock - anything that is sensitive for quality and stability of input power. Point taken, should have told about in the review (this is my third LPS review so I kinda assumed that people have seen previous ones)

@@k4syx so that's not for amp? More for dac and preamp? What's the difference between this and power conditioner then? I have a power conditioner from Amazon and I can hear it improves the sound greatly

@@MasterofPlay7 power conditioner is for your power line (220-240V AC). This is just power supply providing like 12V DC for example. This DC voltage would be the power source for some DAC or headphone amps (or even speaker amps that have external power supplys, though it would more in 24-48V DC range). So kinda different device for different needs: doesn't replace conditioners but will probably slightly benefit from their presence

That is very expensive for what it is.

Are you thinking about the price of parts and case? It's not that bad, here in Europe good case and transformer can be expensive. And compared to price of standard wall wart plug power supply, linear power supplies with low ripple are way more expensive...

My feeling is it is snake oil audio. Many reviewers praise very expensive linear power supplies. Usually no measurements available except at audiosciencereview were it is shown it does not make any difference.

@@rainerbroennimann1563 well LPS doesn't have to be expensive, I'm buying as cheap as I can. Also, it's possible to diy LPS, but the price of the trafo and case is the main component and price wise it may be more or less the same. So no money involved. As for measurements, I've measured all my power supplies for ripple and best LPS was 7mV, Meanwells were like 80-90 (as specced by mfgr) but regular impulse power supplies were like 150-200mV and that is 0.15 - 0.2V. so for 5 or 7V power supply that's quite a lot, and that's AC component present in your DC that should be dead flat. With all respect to Amir (and I like his reviews and I'm a frequent ASR visitor) he doesn't know it all. There's a reason why LPSs exist and why they are superior form of providing power to delicate, precise equipment. Ripple = 100% noise...

I bought a 5V LPS from Aliexpress for my DAC. Very nice construction, but it took the life out of the DAC. It flattened the soundstage and made the music less dynamic. Just because it’s a LPS, doesn’t mean it’ll be better.

Was that LPS by accident BRZHifi 25W? Just came to me that maybe your DAC needed more juice (power for analog output stages) and that was the cause?
