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.

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.

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.

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 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.

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

Switch mode power supplies (SMPS) are notoriously electrically noisy. My router feeds my hifi streamer so I wondered about the impact of cutting some of the noise being fed into the system from this source. This is, of course, still a SMPS (a decent linear 12V supply is about 4x the cost) but it boasts better design and suppression than the very cheapo ‘wall wart’ power supplies that routers come with.So far, so good. The sound is more open, fine detail seems better resolved and bass is better controlled. All this is an indication of a lower noise floor.This is a very good value hifi tweak.I’m keeping it!

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.
