iFi DC Power Supply
« on: 21 Apr 2018, 02:01 pm »
 I just got my Audio Advisor catalog. On page 24 there is a new item called the iFi Ultra Quiet DC Power Supply. It looks like a traditional Chinese made Wall Wart power supply that gets supplied with items needing one. The Schiit products for example. I was wondering if anyone out there has tried this 49 dollar devise with any gained improvement in sound?......thanks Mark Korda

I can't speak to the particular model you mentioned, but if it's at all like their iPower, which has the appearance of an ordinary wall wart, looks are deceiving! To my ears, my iPower sounds quieter than my more expensive TeraDak DC-30W LPS, despite its being a SMPS. Unfortunately it doesn't provide as much current, so if you are thinking of getting one, make sure it is sufficient for whatever device you plan to use with it.

There is a guy over at Computer Audiophile who posted measurements of the iPower along with several other power supplies, both SMPS and LPS, and a 9V battery. In his ripple test, the iPower beat everything but the battery. I'll post a link if the mod will let me (I'm guessing it's against forum rules.)

I use one on a Raspberry Pi 3b+. Compared to the standard walwart it came with, it made a noticeably difference. Nice upgrade for the price.

The only AC item I found that beat the battery was the Astron PSU. The Astron is a well kept secret in the audio world today.

There are always cheap used ones on Ebay. :thumb:


Buy used and if you do not like it, resell it. Not a lot of money wasted.

Any power supply options ppl like for cable modems?  I have a Comcast cable modem going into my Google Ethernet Mesh Network which flows into my DSD Sr.  I'm wondering if upgrading the power supply on that Comcast box would help.  Thoughts?
