Even with a digital piano an iPower2 brings improvements. Notes sound thicker and bassier, with a stronger attack than with the original 12V power supply that came with it.
Hey, just purchased 12v version of this to power BTstreamer, and it has introduced noise and slight distortion to the music.
Also i hear very low hissing in background, Pops when power off. Any ideas?
it is meaningless because SMPS (Switched-Mode Power Supply) uses an AC voltage that is converted to DC internally. The AC input is rectified and then filtered to produce a DC output. The polarity of the DC output is determined by the circuit design, and it is not affected by the polarity of the AC input.
Just dropping my experience with the 5v XPower and the ZEN CAN. If anything was holding back the ZEN CAN, it was the lack of enough current into low impedance headphones. 4amp dynamic current was recommended, but the original SMPS didn't reach that level of current. The X Power does.
Maybe its a bit crazy to add a power supply that costs half as much as the headphone amp, but I CAN say it makes the excellent ZEN CAN even more excellent, and better with low impedance loads.
I bought an iPowerX for my son's Qutest DAC. It made a very noticeable difference. The background is blacker. There is more detail and resolution and there is an increase in musicality. However, a Teradak LPS makes a further improvement and sounds better than the iPowerX. There is even more detail and resolution. Textures are better as are dynamics. I would also like to note that usb cables also sound different with the Qutest. We used an AQ Carbon, WW Starlight 7 Red and an Oyaide. They all sounded different with the Carbon and WW sounding muted compared to the Oyaide which was bright sounding. We settled on a Ghent Audio USB Cable for $40. It sounded the smoothest and had excellent detail without sounding bright.
The iPower series were good; the X Power stuff is another level. I know it greatly increases the cost of the ZEN CAN, but if you are thinking of upgrading your ZEN CAN to something else, especially if you are using rare headphones with impedances lower than 20 ohms, get a 5v Xpower, which has the current needed to allow the ZEN CAN to drive those low impedance headphones.
even if you don't have a super low impedance headphone, the 5v Xpower seriously takes the ZEN CAN to another level.

If your Zen One requires a 5v power supply, I would not use anything higher than that. There are plenty of Linear Power Supplies available from Ali Express. That's where I bought mine. Here are a few-
If you do order one, make sure you ask for the correct size barrel connector.
I own 2 Teradaks and they work great. They made a huge difference with my Chord Qutest DAC and also a Regen. I also use one to power a JCat usb card and that made a nice improvement in sound quality. The iPowerX is a good product and we use one as well.

yeah NEVER use a higher voltage than recommended. I was specifically talking about CURRENT, which while of course related, is a different beast. Bottom line, if it says it needs a certain voltage, give it that voltage. Don't give it more.. you may end up with a fried component.
I recently bought Dacmagic 200M and the seller sold me Ifi Power2 12v/1.8A power supply with it. Now, I’m nervous whether the 1.8 amps is enough for the Dacmagic since the requirements state 2A. Any idea moving to X amp-wise?
