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

This power supply was used to replace an EE modem's power supply (the Smart Hub Plus), in an attempt to improve my WiFi signals on the 2.4 GHz band.It certainly did that - in terms of signal strength, on all WiFi bands (2.4 & 5 GHz) but because the modem continued to drop out with extreme regularity (sometimes for minutes at a time) on every single device (the Hub and all 3 satellite extenders) I had the modem upgraded to the latest Smart Hub Pro - which offers WiFi 7. Incidentally, that has now virtually stopped the drop-outs.Unfortunately the supplied interface plugs no longer fitted the new modem or any of the satellites and meant this product had to be returned, which is a shame.This power supply is clearly well made. I only wish there were a standard power plug format for 12V supplies.

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.

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.

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.

Not going to lie I didnt expect much from this.. but when I say it is nevessary for anyone who cares about their audiophile setup I mean ITS NECESSARY.My K5pro amp hasnt sounded this good ever. Just testing this now with ananda nano and my god the sound is so much cleaner and the texture is much more pronounced.I thought at first this will only lower the noise level but its done much more for me, from what I can hear anyway. I haven’t even done a direct comparison I just put my headphones on after replacing the old power cables for the amp and immediately noticed the difference so would say it is significant and not a placebo.Quite expensive but for what it did for me I would say absolutely worth it.One note, you guys might find this makes the soundtrack a bit darker and increases the soundstage … for my ananda nano this was a great pairing as they are a tad bright for me and this was a good addition.

The FiiO K7 comes with a 12v switched mode power supply, ifi Power X low noise power supply noticeably improves the quality of the music played through the K7

Product had a very positive effect on the sound quality. Background is now more silent. Mids and highs are clearer. The only problem with the product was the socket. I ordered from Amazon uk since there is no stock germany. I know the product has a replaceable socket. I thought there would be switchable multiple socket adapters. But it only has a uk socket adapter. I contacted support for an additional purchase for a eu adapter. Process took sooo long and socket adapter is very expensive including also additional shipping costs etc. I would expect such a product to come with multiple adapters since this a common practice for high qualitya products.

Used to replace a standard power supply for my Arcam irDAC. As other reviewers have noted, there is a definite improvement including this product instead of a basic power supply unit. Better clarity on cymbals and other high frequency sounds, clearer and more defined bass and midrange. Complex choral works you can actually hear the words being sung.
