Thank you for your useful and constructive comment on this new product. I presume you base your judgment on extensive testing of this particular unit, which is only quite recently on the market.
iFi AC iPurifier
One of these arrived yesterday. Nicely made, though the lights and lettering on the end are not exactly horizontal when it's plugged in.
Tried some initial tests, plugging it into the spare socket on the duplex in the wall, and various spare sockets on the power strip. With the system on but no music, and with music playing, I could hear no change whatsoever with it plugged in or not.
After a couple of hours I noticed that the flat end of the cylinder was getting quite warm to the touch. The unit came with a soft plastic white plug in the earth hole, and I assumed it was there to stop dirt getting in. Nothing about the plug/bung at all in the instructions, and not featured in any of the photos of the thing. I removed it, and it definitely seemed to cool down.
Will persevere some more, but with the AC that I'm dealing with, it seems that results will be, at best, subtle.

roberjerman Ac purifiers are just another marketing ploy to get the gullible to spend their shekels!That’s an odd comment. On what do you base your claim? Of all the system tweaks in audioland, AC purifiers are among the most easily tested. Some provide voltage correction and even power factor correction; those can make a big difference in a system’s performance depending, of course, on the quality of the AC in the first place. |
@twoleftears, After spending a weekend with iFi AC iPurifier, I didn’t hear any ‘upgrade’ in terms of lower noise floor in my audio system. The test was conducted with iPurifier plugged into same wall outlet as my QRT system including QBASE8 - MKII, Qx4, a pair of Qv2’s and Qk1’s. To give it a fair shot, I then tried the iPurifier on the receptacle my projector plugged in and noticed immediate uptick in PQ. The colors were slightly more vibrant with increase depth perception and sharpness. After 5 hours of continuous use, I pulled the iPurifier out to see if I can live without it. Turns out, I prefer my viewing experience with iPurifier remain plugged in this outlet. This led me to believe that iPurifier does work as long as you’re not using any other AC purification solution. My QRT system far outweighs the benefits of a standalone iPurifier, which is quite unfair to say the least given the cost difference. May be a full complement of multiple iPurifiers (iFi suggests using at least three) in a audio system yields better results.... For $99, you get over-voltage surge protection along with benefits of lower AC noise. If you’re treating a single outlet or a component, I would say it’s a keeper. And yes, it does feel warm to touch but nothing alarming. |
