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.

Worked well for me: increase in clarity and dynamics, no shift in tonality. I bought some more.

I discovered this gadget yesterday. After some experiments I'm a believer! Bought one already and maybe will buy more in the future. 
It works especially well with digital devices. I have it plugged on the power bar where my class D monoblocks are connected, together with CD player, computer and DAC. The difference is not huge, but clearly audible. Everything now is more clear, less blurred. 
But I must say that among some trials at the shop, it didn't show the same results for every system we tried. It seems the final result is system-dependent.

I bought 2 on a whim. In short, they're staying in my system.

I noticed 4 things in my system: 1) lower noise floor (never realized what that meant until now), 2) more "space between the notes", 3) the "edges of the sounds" extend further, and 4) there's no question about where the "sweet spot" is. 

These are cheap tweaks that are easy to implement (and easy to remove and return if they don't make a difference in your system).
