Hi, I am new here. Got the wiim pro a few weeks ago. I bought for curiosity as it was so cheap. I use it strictly for streaming to an old Neko dac mk2 via spdif and it sound good with my yamaha as-2200 integrated and totem bison twin speakers. I was using it with a ifi power x and it sound good. I recently found a s-booster for dirt cheap on marketplace and tried it. did it make a difference to the "zero and one" data flow ? Yes huge difference, no need to do ridiculous blind tests or useless measurements, the difference in bass texture is massive and sound stage is ridiculously bigger. Maybe I will try the original power supply one day. So do power supply make a difference if only using the digital part ? Answer is an absolutely massive YES.
Test WIIM pro+ with different power supplies

I'm going to assume you are just trolling cause nobody can be that dense and clueless to make such a statement

Yes, you are absolutely right. I tried the WiiM Pro first with the supplied power supply, not so good. I had a power bank lying around, now we are talkin´! After that I tried a Allo Shanti Linear PSU and the sound expanded in all dimensions. Great! (I also go optical out, with a QED Optical Reference Quartz) the sound is miles ahead from Coax out. Enjoy!
I might give another try with the optical out. If I remember its sounded a bit bright.Yes, you are absolutely right. I tried the WiiM Pro first with the supplied power supply, not so good.

But with the optical cable light comes in! So it will be even more bright.

Words fail me.
Digital data does not change, lol. What change is the accuracy of the flow, its all about timing, probably deterministic jitter caused by ground noise who cares...not simple as most bro internet scientist think. There is no mystery. Use your ears.
Most kids in here probably use cheap crappy speakers, so no matter what they do with the front end nothing will change and It is very understandable.And to make the situation even worsei can tell that I'm using with satisfaction also the lan silencer (also from ifi)
Sorry for the ot but i think its someway related to this topic

Edit
Forgot to mention that obviously the system must be revealing enough to bring out those "little" differences

Wrong on both counts.
When you are ready - sometime - make yourself familiar with a) what and how data is transported and b) the concept of „psycho acoustics“…

In theory a bad power supply can influence the timing of the digital signal path (jitter) but the measures done for the Pro+ show a jitter noise level way below what is possible to hear (~ -120 dB), even with the standard power unit. Claiming that a "better" power supply make a "huge difference" is just nonsense.
Any so called high-end DAC will re-clock the data anyway.
Noise from a bad power supply can also propagate to the analog output and to the Coax digital output but again, the Pro+ has been measured to have very low noise with the standard power supply.
Only issue seen is with the WiiM Mini, where the included power brick may have too little power for some use cases.
The perceived improvement is all due to psychoacoustics. We are all influenced by this. Everytime I change something in my setup I think it sounds better. And then, after some times, it gets boring and I change something again. Sometimes just back to the original setup.

Sound change with better or different power is very evident on very resolving system just by listening to it when using wiim pro digital section alone. It is not subtle. Your science is probably good but your measurement ability is not. Making all these assumptions is not scientific. Maybe on day your instrument will be able to detect new variables, that you did not think made sens. My recomendation for people who want to know if power supply make some difference or improbements is ask people who tried it. Avoid people who haven't tried it, it is just commend sens. Is sound like people who haven't tried better power supply say it cant help. Before traveling and choosing a resort I trust people who visited the place more than the others. Lol, sell your instruments and get your self some nice speakers, and a good power supply enjoy music ..

I leave that to the unsecured pseu bro internet scientific that need approval about his lousy speakers.When you are ready - sometime - make yourself familiar with a) what and how data is transported and b) the concept of „psycho acoustics“…

This thread is getting beyond silly.

This seems to be one of those topics that predictably goes downhill in every audio forum. Sometimes it almost feels deliberate.

I didn't make the measurements. Look them up.
In other dimension maybe? This is the usual bla, bla when the you have no good arguments.
I have done that for curiosity. No difference at all, of cause. Maybe my system is not revealing enough!

Could be your speakers ? Could be the amp, I am surprised. You know when a camera lens out resolved a sensor, it does not matter anymore if you get a better lens .My friend own an old unresolving sound kit, I love it, does not matter what he does to his front end, it always sound about the same, and it sound so good and relaxed. I am sharing my observations to help people who havent exprienced it. Keep in mind the wiim pro is a very cheap unit with a plastic case. My honest finding the wiim pro is a fantastic product that be greatly improved with a seperate Power supply and DAC. I don't considered myself an audiophile, my speaker cables cost me 35$ and they sound great and I have tried expensive cables. I had a long and succefull in science and dont care how people make fun of me. I am pro science but this is about music.I didn't make the measurements. Look them up.

I don't understand what you are trying to express here. Not sure if I'm interested in an explanation, though.
Trouble is, all your claims have been made before (by others) right in this thread, over and over again. It's nothing new. I cannot prove that you're wrong. You cannot prove that my system or hearing aren't "resolving enough".
It remains a little miracle how some chosen ones can hear differences the majority cannot hear and nobody can measure. The many different effects and biases that have been scientifically proven to fool our perception are simply the more likely reason for any "miles apart" differences in my book.
