I was surprised to see an impovement in sound from a Pro-ject S2 dac and a Fossi Buletooth dac. It was recommended by the The Hans Beekhuyzen Channel on youtube.
iPower
Max power.
Effortlessly powerful.
If your system’s power supply is unclean, background noise affects your sound quality.
The iPower cleans this up, addressing the problems at both the output and input stages.
It makes your sound flow cleanly and effortlessly.
The power of four.
The iPower has four barrel tip adapters, which means it’s compatible with all wall pin types across the world (UK/US/EU/AUS), as well as USB and centre negative audio adapters.
Music. TV.
Whatever you’re listening to, the iPower smashes through the sound barriers that hold devices back from achieving clear, uninterrupted sound.
Adapt to change.
The iPower makes music come alive with incredible low-floor noise and adds detail originally lost through conventional power supplies that are often just mobile phone chargers that have no regard for quite power.
The iPower is at least ten times quieter than previous iFi power adapters, twenty times quieter than audiophile linear power supplies and one thousand times quieter than standard wall adapters.
At home or abroad, there’s nowhere the iPower can’t go.
Audiophile-standard DC power supply.
Works with virtually any DC powered device.
Just check the correct voltage (5V/9V/12V/15V).
Quiet! Active Noise Cancellation+ (ANC) at work!
Exceptionally quiet power. The measured noise floor is 100x quieter than the Common Noise Filter.
Light and convenient to use.
As it comes in 5, 9, 12 and 15 volts and with pins for the USA, United Kingdom, Europe and Australasia, it can be used all around the world.

Really improves the sound
I got this to use with a Raspberry Pi-based audio streamer. The sound was improved greatly over using the previous CannaKit power supply (which to be fair is far less costly). With the iFi unit, the imaging and soundstaging were clearer and the sound more alive.

Bang-For-Buck certainly, but iFi also punches well above its class.
iFi Audio is a spin-off from the audio heavyweight firm AVM, and much of their technology benefits from AVM’s deep pockets and experience. iFi DOES NOT produce “cheap” goods: Even their lowest-priced components are built like tanks — tiny tanks yes, but SOLID. I have 4 iFi components set up as one of my two computer-audio rigs: They cost a couple of hundred dollars apiece, draw very little power, and produce great sound.
You could put this system into a shoebox, AND STILL HAVE ROOM IN THE BOX FOR FOUR MORE complete iFi systems. iFi’s website is also superbly well-designed, offering new product info, driver/firmware updates, and download-able manuals. Good job all-round.

Sweet rasp pi
The Raspberry Pi is a great computer audio server and costs next to nothing, but the power supply is really noisy and destroys the sound quality. On another webshop I saw the iPower but decided to buy from Amazon for the return guarantee.
Once I put in ipower 5v, the background was so much quieter and the bass was better defined. (I play drums and can tell when the drum sounds like a more realistic one.) Good product, not cheap but well worth the upgrade!
