“My home network has both WiFi and a LAN. The LAN has two unmanaged data switches… nothing special, just a standard 5 port switch from one of the big providers. The ifi power supply replaced the supplied 12V wall wart supply. The results have been amazing. The sound streamed from Tidal via my MacBook has improved very noticeably, especially with MQA master! The picture in 4K on a 77in OLED is also much improved with streamed content whether direct to the TV from the router or via the computer. Tried the device with the second switch which serves a second system with the same result. Super impressive for the money.”

WoW, this is a really low noise power supply. Great for audio (and video) purposes.

The evidence is in the numbers. ifi Power is cleaner, ie less noisy, than supplied 12V power supplies for BT FTTP and my Netgear Switch. You might ask why these two items specifically? The answer is that they provide the power to the internal signal for my broadband. I use Devolo powerline ethernet (cat 7) adapters and read up about issues with power supplies impacting video playbacks on networks so figured that it would make sense to look at reducing the noise floor on my internet source (BT FTTP) and termination NetGear switch in my garden office. The proof is that all connections are up by 20% in the before and after testing. Plenty good enough for me, to give ifi 5 stars for these power supplies. And saving me hundreds by not paying for Linear power supplies. (I also swapped out a 5V supply for my Bluetooth receiver and Phono Stage power supply with ifi power units – Currently doing sound tests).

“Possibly the best addition for any Raspberry Pi based Audio… it’s not horrendously expensive – but it DOES work and lowers the sound floor nicely. FAR, FAR better than anything else – unless you start spending very silly money for limited extra benefit.”

I bought this to get rid of a grounding hum between my DAC and amp. This iFi power supply was to replace the one provided with the DAC and it works a treat – no hum and sound quality is great. A well made product too.

I saw reviews and decided to have a try. I was prepared to see little or 0 impact. I was wrong. Once I connected this to power DAC….what a change. Sound is richer, more detailed, more separated, warmer and louder. I can hear sounds I never thought they existed in the music, songs. If you have a 2.1 stereo set up and you have a good DAC machine, then buy this without hesitation. Well worthy! Thanks

Like: clear, true, clean power supply unit.
Against: none.

Excellent product. Perfect for high quality audio equipment. No hum at all as expected. A little expensive but worth it.

It eliminates power noise dramatically. Strongly recommended.

amazing

I have a couple of these for different audio components, and in my experience they’re at least as good as pricier linear power supplies. Highly recommended as replacements for standard wall wart supplies for DACs, etc.

Brilliant !!!!

I have been suffering from terrible noise on my Cambridge Soundworks PC speakers for years. This got a lot worse recently when I started using Powerline networking. This was an extreme crackling noise. The iFi psu has completely solved the problem and thus improved my quality of life no end! I can’t recommend this product enough.

I’ll give it a 5% improvement for my Amazon Cube with Amazon Music HD.

Improved the upon the soundstage that came using the supplied SMS. Only minor problem was the SMS used a 3mm diameter male plug. Which meant having to source a 2.5mm to 3mm diameter connector, as the range supplied with the unit did not cover this. Eventually found a source else it was £50. down the drain.

I actually used it for a different application to most, I bough it for a Sony PSHX500 turntable. In fact I really do not believe it can do much different to most dacs, as dacs and streamers have already circuit filters but well in the turntable sector one of the first upgrades are linear power supply, yet this not exactly such but neither is my turntable a Rega Planar 3. I just hoped a better switching power supply would mean better pitch stability. I tried it thinking sure I will return it.

Bought this as an upgrade for my Raspberry Pi/HiFiBerry DAC2 HD combination. Audible improvement in sound quality. A bit more space and definition and no system noise. Excellent upgrade to a low cost front end for a high end audiophile system.

I am in the process of tweaking my computer audio system. I was mildly dissatisfied with the audio quality of my Schiit Modi 3 when powered by the PC over a Pangea Premier USB cable carrying data and power. I then began running it from a 2A USB tablet charger. It provided a modest improvement. I read a few places online that this ifi iPower adapter provides clean and quiet power over its microUSB attachment. I bought one and connected it my Modi 3. It provided a greater improvement in audio quality than going from PC power to tablet charger. It’s a keeper.

This combined with the defender+ completely fixed the electrical interference nightmare I was having in my recording studio. Wish I had been advised about it sooner.

A perfect companion for topping d50s.

I am struck by the incredible performance of this 15VDC power supply. I am using it with my Schiit Mani phono preamp, which is hugely sensitive to EMI/RFI and 60HZ loops. But the iFi handles it very well. If you are looking for a quicl fix to a bad noise situation, this little guy gets it done.

This is a very good replacement to any cheap bog standard adapter in its range and this is just one of many they do. The adapter is no bigger than the one it replaces and is far more pleasing as its so quiet, this one I bought to power my ethernet switch and it is a big improvement on the one supplied with it, very pleased and would recommend these as a good step up in reliability and efficiency.

I’ve used it as an upgrade to the wall wart that came with my WiFi router/modem. I have a Roon based music system and anything you can do to reduce the noise floor is worth doing. If you don’t want to go to the whole hog and buy a large linear power supply this is a worthwhile upgrade that makes a difference. Recommended.

Purchased this because of the reviews it’s a stop gap until I can afford a proper Linea power supply

A good match for the Ifi DAC/preamp …worth the money for an external power supply

On my system, it made the sound of my Pro-ject Pre Box S2 digital even better: much faster bass, more detail overall. The DAC seems to have a tighter grip on the music. If you have a Pre Box S2, it’s definitely worth trying.

I bought this because a review of a DAC for a Raspberry Pi said that the audio performance was poor if there was a noisy switching power supply (PS). This devise provides a much cheaper solution compared to a linear PS and it worked very well. I therefore bought a second.

After doing several rips. I substituted a $49.00 12 volt/1.8amp iFi Low Noise Power Supply for a $110.00 12 volt/ 3amp linear power supply from China and found that the music quality output was just as good at 40% of the cost. Strongly recommend iFi’s range of easy, quick-delivery solutions to dirty AC power for appropriate components like a CD ripper

I need to be careful writing this review as I have read many where the author has raved about a piece of hifi only to find it mediocre at best or to find something far better a month later. So I dont really know how to make this ‘just another 5 star review’ of many other top ranking hifi components. Yes mains treatments are subjective but this little wall wart proved very special indeed!

I was half expecting the ipower to improve things marginally, half expecting no improvement at all, especially as i have a system which puts a big emphasis on mains treatment already. My system is: home built pc, Arcam irdac ii, Rupert Neve RNHP headphone amp, Isol8 Substation 2 mains filter, mains cables from Van Den Hul and Atlas.

Quality product. Noticeable improvement in audio definition.

I got this for a Rasperry Pi I am using as a music streamer. In this application I wanted to avoid switching noise and the only alternative would be a bulkier and more expensive linear supply. If you need quiet power iFi has the right stuff. Now to get the 15v model for my phono pre amp.

Purchased the iFi 12v power supply for use with a Focusrite Scarlett 6i6 audio interface. Works perfectly with a very noticeable improvement in soundstage depth and separation. Wasn’t expecting to hear such an improvement so this is a welcome surprise and is the best fifty bucks I’ve spent in a long time.

Used to power my Chord Qutest dac, made a slight improvement (I think) !

I bought this power supply for its low noise output to use on a low noise antenna video amplifier. It works very well and has improved reception for marginal signals. The video amplifier came with a regular 5 volt USB charging supply that was became noisy. This fixed the problem.

Just happen to have Orei DA21 SPDIF/optical DAC and ifi SPDIF iPurifier. Both are driven by this AC iPurifier and boy does it make a HUGE difference! My sound bar is Samsung “el cheapo” type and the built in DAC is not performing at its best. By using external DAC and SPDIF filter made “el cheapo” to “el mucho grande”!

I was introduced to iFi through their Spidf reclocker, which I used for the Chromecast Audio. I was surprised to find that a $12 Cable Matters USB cable running from the stock CCA wall wart into the CCA for power made a dramatic improvement to the sound (even though it was upstream from the iFi reclocker).

So, I figured replacing the wall wart altogether might make a difference as well. There was a difference, but it wasn’t as dramatic in my current setup, which currently runs a builder grade electrical outlet, for example.

The difference this PSU did make was to take my speakers (KEF Q150 standmounts) from a raw sound to a refined sound. Small but noticeable. Also hard to know if a small tweak like a hospital grade electrical outlet might unlock this PSU upgrade further.

I cannot believe how much improvment this PS gave to my system!
I’ve ordered it for my RaspberryPi 3 B+ streamer with Volumio which is connected to schiit modi multibit DAC.
I wasn’t sceptical but didn’t really know if it would actually give so much good stuff..my mind is blown.
since I have plugged it ,the sound is so clear and quiet the background, the bass is tight and just lovely. soundstage got bigger and fuller.

absuloutly loving it and would defenetly recommend! Buy one! now!!

Originally, I got the iPower unit to use with a MiniDSP NanoDigi that I use as a three-way digital crossover going to three Schiit Audio Modi 3 DACs that operate in parallel. My expectations were pretty low for the iPower because, even if the iPower improved the sound of the NanoDigi, I assumed that the output would still be limited by the stock power supplies feeding the Modi 3’s. Even in that configuration, the iPower improved the sound of the NanoDigi significantly. Compared to the stock wall wart, the iPower did this:

I’ve used these PSUs before and have several of the available voltages. However, I didn’t have a 9VDC variety, and iFi was my first choice. Works as directed for clean DC voltage when you need it. Recommended.

This is the best $50 Ive spent on home audio. As soon as I plugged it into my iFi Zen and hit play, I was shocked with how good it sounded. I unplugged it and tries the Zen alone. Tried multiple headphones. And the difference is staggering.

With my Hifiman 4xx, the Zen Dac sounds CRYSTAL clear. It’s almost unnerving.

Regardless of headphones, I’d HIGHLY recommend this addition. With the Zen Dac it takes the quality to a whole other level. I’m hoping it would do the same for K5 Pro, THX or any amp you have.

Helped my Shift modi3 dac achieve better sound gaulity don’t know the science behind it but it worked!

Call me a believer now. Have the Pro-ject Prebox 2 which is a great DAC for the price which has a 5 volt power supply that does well but many have said ( a better power supply would turn your $400 DAC into a $1,000 DAC. I thought it was worth a try and boy were they right.

Soundstage improved dramatically without losing detail & @ higher than normal volume the DAC didn’t run out of steam like before. There is reduced noise which I first mistook for increased detail. My home has decent power yet I heard quite a difference so I’m not sure what result can be gotten from a noisy power line.

The power supply cords. are needed for speakers to enhance the sound quality lost the ones that accompanied the speakers when I purchased them ifi power supply cord met my expectations took a long time to find correct cords

Really worth it! Working great with my d/a converter! Clean up the sound nicely!

Hi end +++

Perfect

The difference with the standard sources is considerable, regardless of whether there are better ones but that is at other prices.

I am using this (15v version) to power my DX3 Pro DAC and headphone amp. I already have the 5v version powering my Chord Qutest DAC in my main system. It is much cheaper than buying even the cheapest Linear PSU and has all the flexibility you will ever need. Even the Topping upgrade PSU is nearly double the price.

Does it improve the sound ? Yes, I believe so. I was a bit of a cable and PSU skeptic till I moved to a dedicated PSU for a previous Chord DAC and heard an immediate benefit. Since then I have tended to upgrade PSU s and power cables but avoided silly money options. I suspect the law of diminishing returns kicks in early with this stuff. I use MCRU linear power supplies for my more expensive components and these iFi units for others. I dont think you will be disappointed.

Worthy investment.

The product paired with idefender 3 produced a much punchier sound than idefender itself. I compared it against a meanwell medical psu and two powerbanks. This ifi beats all with meanwell on the bottom.

It’s only downside is the price. It’s a little expensive but comes with a bunch of accessories, which kinda justifies the price if you can find places to use them.

Frankly I wasn’t expecting such a good improvement over meanwell. A pleasant surprise!

Does exactly what it says, best product I’ve used for cancelling hum, noise etc from guitar pedals.

Got the 5v version and changed out the stock adaptor supplied with my Chord Qutest DAC. Really big improvement and worth every penny. Will not go back.

Includes all kind of adapters. Excellent.

Amazing difference in my pi based streamer! I was shocked as I felt how much difference could this even make? I could immediately hear a difference in depth and quality of audio. I’ve been using this streamer for over a year with the stock power wart and wish I would have switched sooner!

Raspi3->JustBoom Digihat->Schiit Modi3

Nas drive into hifi system improved over standard power supply

I have iFi on both of my Raspberry Pi, one music server and one player (with DAC Hat). I was already impressed with the improvements to the sound quality and reliability (both well over a year old now). Today I added a 9V version to the ethernet switch between them (cheaper than an audio grade switch).

I’m hearing yet more detail (I didn’t think there was anymore to extract) and there is more space between the instruments. To my ears it sounds more analogue and voices are better defined, I’m hearing things I didn’t know were there!
I now need one for the ethernet switch in the living room for the main audio player, FireTV, Smart TV………

Excellente alimentation.

My TV Bluetooth audio extender had a “hum” on it. Replaced the cheap charger/supply it had with this much better supply. Now no more hum! I can leave it plugged in all the time.

A little expensive but if you value top sound quality then there is no alternative. Use them to power my Chord Qutest

It took’s my turntable to another level.

It took’s my turntable to another level.

Originally purchased for my Raspberry Pi audio player I assembled, I turned out using it to replace the power supply of my Logitech Squeezebox Touch, which seemed to start suffering from audio dropouts when my refrigerator turned on and off (as well as other power-hungry appliances). This product did the trick and I feel better about this power supply than a cheaper one for the SB Touch.

Bottom Line: It’s a very well-built power supply that does the job.

very good

I already have an IFI Audio DC Purifier 2 sorting out the power to my valve phono stage which I have been very happy with.

This new supply is supplying power to a valve pre-amp which is a vast improvement over the standard SMPS. Highly recommended.

I recently discovered iFi products. I bought the iFi PowerStation which is just phenomenal, the iFi iPurifier3 for my DAC which has taken the sound of my hifi to a level I never dreamed possible, and now I have purchased this iPower SMPS (switch-mode power supply) to power my DAC.

It makes the sound so clean and open, takes away harshness and adds smoothness and a beautiful warmth to the sound. The backgrounds are silent.

This iPower is way better than an expensive linear power supply I tried recently. I cannot recommend this enough and the price is fantastic for it’s insane quality. The company are fantastic to deal with too.

A little background – I set out on a quest to get the best sounding and looking high definition sound and video I could muster on as little budget as possible.

I started with a $750 Furman power conditioner for all my audio/video/cable box/modem/router/switch equipment in my main entertainment center. BUT when you plug in cheap wall warts, even if it is plugged into a $750 power conditioner, in a way you have defeated the power conditioner, because they are AFTER the conditioner. What to do?

I ordered these (3 of them after trying one) for the last generation of Chromecast Audio streamers and 2nd generation Chromecast Video streamer.

As you probably know, noise from linear power supplies is much lower than switching power supplies. If you want to know more, put “linear vs switching power supply audio” into a search engine.

Anyway – this is a high quality LINEAR power supply. It tightens sound, represents the soundstage more accurately, helps remove artifacts and distortion from video, etc., etc.

Try it – You have 30 days to make your decision. BTW – look at the other voltages they make. You can clean up your cable modem, router, Ethernet switches, on and on. EMI/RFI is some of the most difficult noise to remove from video/audio equipment. This power supply is an inexpensive solution.

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.

Good product!

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.

Does the job admirably

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!

Good quality. Made a big improvement when powered direct to iqaudio DAC.

Incredible value and quality. Improved my Chord Qutest dac and also the raspberry pi computer power supply when used with The Allo Digione Signature network streamer board.

Using this with an TP-Link 8 port switch. I decided to try this as I connect a PS-Audio DAC w/Bridge II using Ethernet as I found WiFi wasn’t as stable for 24/192 6mbps sources in my home. Wasn’t sure what the results would be using the iPower but for the price it was worth a try. I have to say I don’t understand why but the results were substantially positive.

What I had prior sounded really good, but with the iPower it sounded like I got a new DAC. Soundstage has snapped into more focus, and tighter, fuller, and lower bass. Vocals have more presence. It’s not just me as friends have asked what changed. Impressed but unsure why it worked so well.

The 15v ipower has enough amperage to work with the expression Porject table. Just be careful that not all work as some have higher amps. But the main thing is the expression gets a blacker, darker and more soulful background and for 49 small ones it isnt too bad.

Id prefer a better looking power supply but we cant have everything. As amazon lets you return then just try it and see if you like it. No risk so Im a happy camper. Bingo the upgrade!

Works well, good product, I would recommend it.

Very clean power output for delicate sound frequencies! Sound have bought this for all my previous audio equipment years ago. Simple, effective, and great value.

People have been talking about these power supplies for years in the online audiophile forums. I never had a need for one until this week. I purchased a 12v model to replace the power supply that came with a very inexpensive tube buffer I bought on Amazon earlier. My digital playback chain is currently Oppo 105 (analog out) > FX Audio tube buffer > NAD 386 > Kef LS50s on properly weighted Target stands. Not cheap gear at all. Cabling is all quality stuff.

I stuck this cheap ($35) tube buffer inline just to play with it and see if it had any effect on the sound of the Oppo. It did, in a very nice way, too. Having spent so little, I thought I’d finally get around to trying this new buffer with a properly built power supply with a design goal of low noise and improving audio performance. OK, it’s kind of dumb to spend $50 on a power supply for a $35 component. But guess what? It made a difference. A big, noticeable, one.

As I’m writing this I am listening to Jazz super-group Hudson’s 2017 self titled release. The tube buffer alone added some nice amount of air, and a richness to the somewhat lean solid state sound of my smaller office stereo. I don’t do any critical listening in the office, but I was actually surprised at how much “more” of what the buffer was doing when I put this iFi PS inline.

This product did exactly what I was hoping it would do. It made an improvement. Just to be sure, I put the original PS back and was met with a pleasant, but much less “ballsy” (for lack of a less humorous term) sound. This one’s a keeper! If I decide to buy the much more expensive iFi iTube2 buffer it already comes with one of these. But, I’d be happy to put it on any other DC powered audio gear without hesitation.

Like many before me I came to this on a friends recommendation to try and improve a good wee Chord dac that unfortunately comes with a functional but rather cheap/nasty power supply accessory. Put simply it works, I would not claim huge sonic improvements but it is definitely a very good upgrade for such a small investment.

Excellent Product

From being sceptical and expecting any difference to be minimal or inaudable I an delighted with the improvement to the sound. A much more spacious sound with instruments and vocals having a more solid presence in the room.

Used a 9v version iPower Low Noise DC Power Supply to power a Matrix X-SPDIF, it worked very well and I’m happy with the results.

Clean power from a wall wart. It works. Instead of buying a costly linear power source for equipment, get one of these at one third the cost. My SMSL M8 sounds must better now compared to when I used its original power source.

Knocked my socks off when I used it on my allo digione player. Worth every penny! I’m not kidding. I thought it was hype, I was wrong. Made my digione sound like $500+ audio equipment. It made the individual sounds more distinct and clean, guitars more crisp, and the soundstage less compressed. It made music sparkle. I know this sounds fanciful, but I just can’t describe it an other way.

I am stunned by the difference. And hard pressed to understand how so simple a mod can result in such an improvement in all areas of the sound.
I have a Soundsmith Strain Gauge Cartridge system that uses 2 wall warts to power the integrated Pre amp. As soon as I get the cartridge back from re tipping I will try these babies on that side of the system. I can’t wait to hear the results..and will report back when I have.

I was a bit skeptical of how much this power supply could improve the output of my Hifiberry DIGI and was blown away.
This is a very impressive improvement over the base Raspberry PI wall wart and a highly recommended purchase.
It has greatly added depth and clarity to the soundstage which I was not expecting.

For reference I am using this in the following system on my Desk:
PSB Image B4
Dayton Audio SUB-1000
NAD 3020D
Raspberry PI 3 B
HifiBerry DIGI
Coax from DIGI to NAD 3020

Love this product. I’m using it with a MiniDSP Dirac Live series DDRC-22A room correction system. I liked my miniDSP before the iPower, but I loved it after. Immediate and noticeable improvement in high frequency detail and “air”. And overall my system is just more enjoyable to listen to. Some might consider the iPower to be an upgrade, I think it’s actually required. Be sure you’re getting the best sound you can get…the IPower is a small incremental cost to the item it’s powering. It’s totally worth it. Seems to be well made and it comes with many sizes of connectors to ensure it’s compatible with most every device. It’s hard to go wrong with this product. Clean, quiet power is important to good sound and this device will show you just how noticeable the difference can be.

Perfect upgrade power supply for my Grundig Satellit 800 Millenium.

Most of the cheap replacement power supplies produce lots of electrical noise. In contrast, this appears to be an excellent low noise power supply
