I got both of them on an impulse buy when I saw them listed on Ali. These are not expensive and I was curious if they really can improve quality of cheap power supplies. As a side effect I’ve learned that Fosi power bricks are quite good on their own actually 🙂
But yes: it works and it can be measured.
No magic, simple science.
I got mine from this shop (lowest price, I know, I’m just a cheap guy 😉

Also check here for 5V version too:

Check both shops as the stock varies as they go.

Nice to finally see your face for a change. 😁. This should be easy to DIY with better capacitors.
Would be interesting to know suitable capacitors for upgrade then 🙂
DIY is allways fun 🙂
Thanks
Please do make a video on that oscilloscope! Thanks in advance…
Yes great to see and I did learn again. I know that specialized lineair power supplies are doing their job by improving the sound. Greetings. 🙂
Eventually DIYers understand there is not such a thing as Linear Power anymore just CLEAN & Ultra Clean.. thanks for the Video
this is becoming my favorite channel thank you, didn't know they existed, now i have to know how low can we go if we daisy chain them, i know you thought about it to 🤣🤣🤣🤣
Cool! Is there anything like this that can work with 5v?
Very interesting!…extra capacitance is a good thing. Would it also work after a linear power supply? Dc to dc. Or would it even be helpful/needed in that scenario? Thank you, learned a lot here 🙏🏼
Where you using a x1 probe setting? I'd like to see the ripple when the supply is under load.
What is the total capacitance which could be measured?
Those caps look as though they are second hand relics from a previous life.
Have you heard of the Canadian amp designer/builder Angela Gilbert Yeung (Blue Circle and Gilbert Yeung brands)? They build massive capacitor banks into their amps as well as building external capacitor banks to add additional capacitance to their designs as well as some Yamaha amps that they modify. They have a test bed amplifier called 'Pinky' that currently has 2630 farads and can run for 24 hours without mains power.
Nice video, as a remark we can add that the power ripple increases with the increase of the current load on all powersupplies. So it might be better to measure with a load like a Dac attached to the power supply (without and with the Hades attached) for practical values and comparisons.
awesome, gadget that works with no snake oil
Yes there is a 5 V version too
Too bad can’t use on your class d amp
Can you add multiple filter banks to reduce ripple even more?
what would the ripple of a 12v portable battery pack look like?
A DAC that needs this isn't a well designed DAC. Those caps are unknown and probably some cheap junk honestly that will fail in a few years.
Problem is not only ripple but also switching frequencies of power supply. The ripple is always way too much for DAC, multiple stage CLC filter and ultra low noise LDO (after buck conversion regulation) will make better job. Look at DIYAudio and don´t buy this crap.
Octave has a similar thing that called “black box”. It have lots of capacitors inside big as soda can. I have Octave V80se amp and a super black box and difference is significant.
I made a few of these myself to connect between the psu and Squeezebox streamers. A really big bang for the buck. Just remember to connect it as close as possible to the power input of your device. Cut some of the cable length off.
WONDERING is there a product that works with the higher power 32 and 48 volt power supplies?
Thank you for an interesting suggestion
Nonsense! Let's cut the crap! Putting cream on a pig will not turn it into a cupcake! Trow away that brick as far you can and build a linear power supply! Yep it's more expensive, Yep it's more heavy, but the quality is there! Clean DC supply with lot of reserve and reliability.
Would daily chaining two or three units improve the outcome ?
Interesting video. Thank you! How can I be sure that the barrel socket will be compatible with whatever switched power supply I connect it to?
They should be doing a usb power version
What happens if you use the bigger version on a device that needs the smaller version? Any risk from wrong combinations?
Sold Out 12V 😢
