iFi iPower X - Low Noise Power Supply AC/DC Adapter – Upgrade Your Audio/Video/Electronics (5V/3A)

I had already tried a iFi Power 2 on the DAC, which improved dynamics and detail relative to using a 30W USB 3-Port Mains Adapter Plug which I had purchased to power both a Wiim mini and a S.M.S.L Sanskrit 10th MKⅢDAC. Purchased the iFi Power X to use on the DAC and move the Power 2 onto the Wiim Mini. Much bigger improvement with the Power X on the DAC than the Power 2 . Sound was more spacious, fuller in the bass, significant increase in detail. These improvements were really unexpected. The sound from Amazon HD streaming is really impressive via this combination of Wiim mini, S.M.S.L Sanskrit 10th MKⅢ and iFi psu's (also QED Performance Graphite Optical Cable 1.5 m used between Wiim mini and DAC) If you have a usb powered DAC this psu is definitely worth the asking price.

Been into hifi for 40 years,was sceptical on this power x for the price,but its definitely made improvements in sound with my streamer

Not cheap, I now have 3, 1 on ifi zen 3 phono, transformational to sound quality over supplied cheap wall mart. I have 2 very revealing high end systems, so the power supply difference is very noticeable. On an unrevealing basic system it may seem to make little difference. And given it's price would seem a waste of cash. The other 2 are on the douk meters (the round ones). They have turned them from fun meter bling to quite usable input expanders, with little loss in musical quality. Good kit but pricey. Worth it to me. A bit cheaper it would be 5 stars.

I bought this PSU for my ifi Zen DAC (v2) which by default takes its power from the USB circuit of the connected music streamer, in my case a Raspberry Pi running MoOde. Having connected the PSU I immediately noticed a huge improvement to the soundstage of my system as well as an improvement in clarity and separation of the different instruments. £109 is a large investment for a PSU and I was more than ready to return it if I didn't feel it was worthwhile but it didn't take long to realise the improvement to my listening experience this made was well worth the money. I haven't done any A to B testing with other PSUs and it may be that the addition of any PSU to the Zen DAC would be beneficial but the iPower X has a a significant number of features that are designed to give you the best possible power delivery to sensitive electronic equipment and from my personal experience it works incredibly well and I'd be more than happy to recommend it.

I use the iPowerX as an upgrade for my iFi Zen One Signature DAC, prior to purchase I contacted iFi regarding expectations their response was that it depends and it could be an improvement or it might be imperceptible - they also suggested buying via Amazon for easy return if I didn't like it. So in a way my expectations were low - but both my previous iFi products have been excellent and thus I bought it. It didn't take very long maybe only around half a minute to think "this thing stays" - slightly better tonality, quieter backgrounds and instruments seemed to sound more solid and in the room. So I am very pleased with this.

In summary: it worked! swapped my streamer 5V power supply to the iFi unit. Instant improvement.

I bought this to supply power to my Topping E30 then E50 DAC. Rest assured on both occasions it managed to clean the up tracks, remove any hissing and managed to add some separation in vocals and instruments. Of course that made the listening experience much more enjoyable not to mention the ability to drive your speaker at increased decibels. The product comes with a multitude of different plug types for your country. If you are directing sound from your PC to an external DAC this really is a worthwhile investment over a 5 Amp generic USB charger.

I bought this especially as ALL switching power units, large or small, will generate RFI hash (noise). It is used to drive my KIWISDR receiver and low low noise is vitally important in that application. I was planning to buy a old fashioned LINEAR (non-switching) unit.... but they would have to be sourced abroad with all the logistics that entails. So... I gambled and bought the IFI Power X. Works a dream .. noise is very very low indeed. Yes.... the unit is expensive, but in this life ? You get what you pay for. Highly recommended. Albert

De doos die ik ontving was al open geweest. Te zien aan een los stikker. Waarschijnlijk terug gestuurd omdat de voeding niet werkt. De verkoper verkocht de voeding zonder te testen weer aan mij. Testen is in dit geval in een 230V contactdoos duwen. Als ze dit gedaan zouden hebben hadden ze gezien dat de LEDs niet oplichten en er ook geen 5V uit komt. Niet erg moeilijk maar niet gedaan. Bij mij werkte de voeding dus ook niet. Ik heb de 230V eu-stekker verwijdert en 230V direkt op de contacten gezet en de voeding werkt weer. Mijn conclusie is de verkoper zeugt maar ifi ook door zo'n zwakke stekker verbinding te maken.

Use this as power supply for my Primare NP5 Prisma. The improvements in sound in above expectations: a more clear soundstage, more details and drive.

Ich habe dieses Netzteil an einem Zen Air Can!?!? angeschlossen. Und ja, das Netzteil ist teurer als der Eigentliche KH Verstärker. Kommen wir aber mal zu dem: Warum dieses Netzteil? Beim Air Can ist leider nur ein USB Adapter dabei. Über den PC USB eine Katastrophe. Der KH Verstärker war zwar lauter, klanglich aber schlechter als mein integrierter PC Sound. Günstige Netzteile brachten auch nur eine leichte Besserung. Erst ein 3A USB Handy Netzteil funktionierte zufriedenstellend. Der nächste Schritt war ein entsprechender DAC um den Sound noch ein bisschen zu verbessern. Nach diversen Tests mit MF V90 Dac, Dacmagic 100 und Dac Box S2 ist es der Zen Dac Signature geworden. Dieser wurde nun mit diesem Netzteil ausgeliefert, so dass es nahe lag es mal an dem Air Can zu testen. Der Unterschied war deutlich zu hören. Also bestellt. Der Finale Test am Zen Dac Signature und Zen Air Can (beide jetzt mit dem iPower X) glich dann schon fast einer Offenbarung, dem Air Can wuchsen richtig Flügel. Ich möchte mich nicht mit diesem dynamischer, detailreicher, breiter oder tiefer Geschwafel aufhalten. Ein gutes Netzteil hat immer seine Daseinsberechtigung. Nicht umsonst legen HIFI Hersteller bei ihren Komponenten sehr viel Wert drauf. Und genau so verhält es sich mit dem Ifi iPower X. Ich selbst vermag nicht zu analysieren, ob die Elektronik oder sonst etwas gut oder schlecht ist. Ich kann nur sagen, dass das Netzteil bei mir super funktioniert und zur Klangverbesserung beiträgt. Von mir eine klare Empfehlung. Meine Hardware: Asus MB mit RealTec HD Sound, KH Hifiman Deva Pro wired balanced, Ifi Zen Dac Signature, Ifi Zen Air Can, Nubert NuPro Aktiv LS, Oelbach Verkabelung

Ottimo alimentatore, abbinato ad un ifi zen phono fa il suo dovere ovvero abbassa notevolmente il rumore di fondo altrimenti troppo invadente, specie con testine dall'uscita molto bassa (nell'ordine dei 0,12 mV); i prodotti ifi audio si dimostrano ancora una volta all'altezza delle aspettative e dall'insuperabile rapporto qualità-prezzo. Consigliatissimo!!!!

… das meinen Pro-Ject Kopfhörerverstärker erst zum „Beimirbleiben“ überreden konnte. Das Gerät beseitigt bei mir zuverlässig sämtliche Störgeräusche! Einen Stern Abzug gibt‘s für den vergleichsweise hohen Preis, die überflüssige, sehr helle Beleuchtung und das m.E. mickrige Garantieversprechen von gerade mal einem Jahr.
