Power Supply recommendations for IFI Zen Stream

Hi folks

Currently, my ifi Zen Stream is powered by the ifi iPower standard power supply. I was thinking about what a Linear power supply would do to the Zen Stream (e.g. the iPower Elite)

Did anyone try a Linear Power Supply with the Zen Stream?

Is it even worth it or is it overkill and an ipowerX is just fine?


There are a number of recommendations of LPSU in the Zen Stream thread. A number of users have said it improved the musical output.

Most of these LPSUs cost more than the stream.
Got to say I have been happy with the 15v that came with my early model.

Edit: just found the thread and realised I created it :grin:


I have no experience with this gear, but in general I can recommend Farad Super 3 Power supplies,
It might be overkill but deeply system dependent, maybe worth a try.

Hey Michael, thank you!
I know the thread but with around 900 replies to mixed topics, it is kind of a longer read :slight_smile:

I know, I forgot how long it was.
I can say that there are several recommendations for LPSUs including the Farad in the thread.

Anything from 9v to 15v seems to work fine with a lot of variation in finding from users on the threads who have tried the different power supplies and the results from them

Hi Xtal,

The ZS’s voltage input range is from 9V to 15V which means it will re-regulate it internally. The result could be better, or worse (if you spend $$$$ on a power supply by cost-vs-effectiveness perspective). So I personally think just go with the power supply unit shipped with original package, or no more than iPower 2.

Btw, i have never try the bundled power supply, so can’t comment on the comparison.

This has made my system sound significantly better - cleaner, more open and dynamic, and video is better to. Mine powers the Zen, a TiVo, my router and a Fire stick. I tried the Zen on the 12v tap but prefer the sound at 15v

If you have multiple DC powered devices, the HD Plex is worth a close look. Note that the fixed outputs can be customized for your needs. Mine has two 12v taps
