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.

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

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 have used my 5v model as a USB supply for a streamer and a phono pre amp. In both cases it pretty much ELIMINATES (not reduces!) the hiss you hear at high volume, and produces a genuinely noticeable sound quality difference. It's dear, yes, but it works like a charm.

I bought this as an upgrade to my WiiM pro streamer. I run a decent hifi with good quality dac.There is a good improvement in detail and the dark is more obvious. Not the cheapest so 4 not 5 stars.

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!

Noticeable improvement in the top end plugged into my wiim pro plus, illuminated plug distracting and not necessary, a worthy upgrade for the money.

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.
