Five power supplies for the WiiM Pro+

The WiiM streamers deliver great value for money and are upgraded by many using an external DAC. But what if you replace the original power supply with a better one?

I have always enjoyed your content, Hans. I have just bought a Wii Pro Plus and an IFI Power 2 based on this review for my old but dead capable 'semi' smartspeaker B&W A7. It arrives tomorrow. On system 1 I run an Auralic G2.1 streamer with an aftermarket Hoer Wege PSU feeding a Denafips DDC and Terminator II DAC with expensive i2S and clock cabling and Network acoustics LAN components, among other expensive audio jewellry (the Auva EQ footers are a recommend of yours I am enjoying also). I'm not expecting remotely similar audio to my setup 1, but a fun office room and convenient streamer. Anyway, to my point: you are so gracious with your replies to people's questions. I ask no questions, just wanted to thank you for all that you do for our community. A real gent, we salute you

Thanks for the information, I purchased the ifi ipower2 for my WiiM pro plus, I can definitely hear a big improvement over stock usb power. This is my first time hearing a low noise power supply. My set up:
wharfedale 12.2
Yamaha A-501
WiiM pro plus
Tidal connect

Took your advise and installed the iFi iPower 2 to the WiiM Pro connected to an external DAC. I could not believe there would be such a difference made by a power supply. Thank you !

I have 2 SBooster power supplies, one for my ADOT fibre optic kit and one for my Chord MScaler. I was fortunate enough to be able to try both prior to purchasing them and was extremely surprised by the level of improvement.

Great video! I'm an old analogue guy and am doing my homework to figure out a good DAC/Streaming option to feed into my 80's era stereo set-up. I'm well aware of the effects of power supplies on older equipment, but am clueless on how they affect the modern digital gear. Your explanation gives me a lot of good information to go on. THANK YOU!

Another super fascinating, helpful & insightful video Hans. appreciate the clarifications and absolute descriptions you were using to describe the sound. I have seen a few DIY RPi PSU's using super capacitors specifically to improve the delivery of the DAC HAT boards.

Thank you for the comparison. Before I saw this video I had purchased the iFi Power2 to use with my WiiM Pro and Pro Plus. Will watch again and see what more I learn. Would be nice to rate each of the power supplies on a scale say from 1 to 10 to help us better understand the performance improvements relative to each other.

Thanks for another great video.
I've been watching your channel for around a year now before I bought my first headphone setup, Sennheiser 660S2 with Ifi signature dac and amp, each with a ipower 2, and was generally happy with the sound. But there was some harshness, too sibilant and some glaring quality that was fatiguing. When I got my wiim pro yesterday with the ifi 2 power supply that harshness was all gone! It now sounds sublime to my ears and I am very happy about my purchase thanks to your very informative videos so I would like to thank you for everything.

Hans, you're a star (as is Tarun, The British Audiophile). I have a WiiM Pro Plus hooked up to a Mojo, which fed my Denon PMA600ne amp. I could barely hear the commercial freezer/compressor/pump come on in the barn through my Br03 speakers, but when I acquired my Grados it was more obvious, and then I started thinking I could hear a very, very faint hiss.
Imagine my joy when I saw your video, which could have been tailored for me.
An iPower 2 was just delivered which I've plugged into the WiiM. I am staggered by the difference, I'm not even going to ask my wife to keep swapping over power leads, the difference is incontrovertible. On the strength of that I've ordered a 6-way power strip that won a What HiFi magazine award, for a modest £40. Fortunately my pockets, and my wife, will prevent this from becoming an obsession, but I can't figure out how the barn circuit is getting to the house circuit. Forget it and turn the music up!
A million thanks.

Thanks for a great review. One thing that I hadn't thought about before, but stuck me from your video was the use of the ENO to filter the Ethernet connection. I hadn't given it any thought, but I guess it makes sense that there could be noise on that signal path. It gives me a whole new area to look at (i.e., Ethernet filtering and audio grade switches).

I have Wiim Pro plus and just ordered the IFI. I may get a sbooster down the road but I need my new speakers 1st. Thanks for the great review.

[Steven-cscw]

Thank you again Hans for another informative and useful video. I had the same experience with the power supplies and WiiM Pro. I have both the LHY 5v LPS and the ifi2 5v PS, I cannot tell the difference between the two. But, they did have an overall positive impact on the sound, as you stated.

Hi Hans. I bought the Sbooster 12v for my Nokia Streaming Box 8010.
I was curious and skeptical!
After I connect Sbooster I ear immediatly the diference for much better!!
You know, the sound is more rich, pleasant, more bass freq., more delicious. NO FATIGUE.NOW I ENJOY LISTEN FOR HOURS!!!
THE VIDEO ON MY LG IS NOT FATIGUE FOR MY EYES AND BRAIN!!!
These days only listen to youtube music videos!
APPLE music is spleeping now.
Thanks for your GREAT
I USE A RX-A6A>AT4007>FOCAL826D

Hello sir, is there anything wrong if the power supply is connected to the same multiplug as the amplifier, CD player...

[Grain]

I'd be interested to know how choice of power supply affects the Wiim's sound when using it with an external DAC.

[Seegurke.]

Fantastic video, very helpfull and great presentation.
The way you respond to almost every comment is impressive, takes a lot of time.
Great channel.

[jonpatrick]

Hans, you're the, "Real Deal" in the Audio Equipment World. Thank you

Hello...nice review, and thanks for tip...I have Wiim pro, via coax out to Marantz hd dac1, via analog out to my amp Musical fidelity m5 si, with b&w 703 s2....Today i get ifi I power mkIi..., and I can say it is a big difference in sound...really big improvement....👍

[AlexAnikin]

How would the results change if WiiM Pro+ would connected to DAC first, like dinafrips, over toslink which connected to an amp over RCA? I understand interference is still a thing, but these PSU can have different results.

[johnkom]

AS others, I say thanks for comprehensive review.
