iFi iPower2 - Low Noise DC Power Supply - Upgrade Your Audio/Video/Electronics [12V / 1.8A]

As I write this review I'm only half an hour into using the power supply and it's made a big difference. I've built a hifi system form older high quality component. Refurbished and improved them to make a very nice system. Quad 66 preamp, Quad 309 amplifier, Mission 773 speakers fed by a Wiim Pro plus and a Rega record deck. The Wiim always sounded bad in comparison to the vinyl.I've always bought good speaker cables so realised small things can make a big difference but have always been a bit sceptical about cables and accessories that claim to improve the sound especially when they involve a reasonable investment. However, purchasing high quality (expensive) cables to connect the components has made a big difference. So I thought it was worth a go at improving the Wiim with a power supply. I had tried it in many USB supplies. They do sound different but none sounded good.The difference the iPower supply has made to the Wiim Pro Plus is remarkable. Music is tight and controlled with a nice rounded bass. I'd thoroughly recommend it on high end components before you decide to try a more expensive streamer.

I have several pedals that dont like cheap switch mode power supplies where the switching noise comes through with the signal. Although this power supply may seem expensive, for how it performs, it's worth every penny! It is as noise free (electrical noise) as a high quality low noise linear power supply. The lead is also far better quality than the usua onesl. I tried powering ten various pedals simultaneously and it worked flawlessly. If you want noise free effects, thoroughly reccomend getting one.

It does make an impact. I am using it to power the internet router. Picture seems better (darker and smoother background) and the audio has improved, too.

Bought this for a lacklustre sounding WIIM MINI. Noticeable for me, had been the lively sounds stage. The highs sounded much more refined to my ears, the lows much more punchier cleaner and distinct. Happier with the sound improvement.This is the second ifi power

This is a well-designed product that fulfills its promise of ridding an audio system of noise emanating from the mains. I echo the other positive comments from users. By eliminating unwanted noise the music seems to have a greater sense of micro detail, added width and all round presence. I notice that some user have commented on its high price but I think that for the difference it makes to a system its cost is fully justified.

Purchased as an upgrade for my Wiim Pro Plus, worked a treat. All aspects of the output sound improved, clarity, sound stage, bass weight. Don't get me wrong, this was only a slight improvement but along with other tweaks I've made the cumulative impact added up to being worthwhile.

Good quality ultra low noise PSU. Noticeable improvement, nuff said.

I had my doubts that replacing the Ifi zen phono preamp supplied generic power supply unit with the uprated Ifi Ipower clean supply unit would provide any audio benefits. However, having taken the plunge by buying one, I did hear a subtle but significantly improved sound quality. This was especially noticeable when using my Ortofon Quintet blue & Audio Technica AT-C09XEN moving coil cartridges. There was greater definition, quieter backgrounds with an improvement in dynamic range & cleaner transients leading to a less forced presentation. It was not as apparent with my Audio Technica AT VM95SH, Ortofon 2m blue & Nagaoka MP110 moving magnet cartridges but still there was a slight improvement. If you are trying to maximize the potential of the Ifi zen phono preamp & you have a revealing hifi system, then this is a worthwhile upgrade especially when using MCs. Recommended.
