What products you'd like to see WiiM produce?

[Brantome]

But! We've had it here before and I confess that I very often know and accept that there is no audible difference. But nevertheless I spend much money for look and feel. Helps me to have even more joy on music.

It’s human nature to a degree - if you spend 500€ on a cable, you’d want it to sound better than a 10€ one, so it does

So basically you want the WiiM device to be a server, doling out any file it receives from streaming services?

@wiim good luck with that!

I Heard the differences with my Friends, not small differences but i respect your points of view

Here’s a conundrum. You have a media streamer with no internal DAC. It has coax, optical and USB out. Is there any possible argument that the power supply can make any difference to SQ?

Sure, all electronics are influenced but i say this on the basis of many direct tests in which we have interchanged the power supplies to different digital devices. I can't answer you scientifically.

 

[d6jg]

It’s termed - Expectation Bias - and in HiFi increases in direct proportion to the amount of money spent.

Is water purer if it comes out of a gold tap?

I deliberately said no DAC so nothing analogue in the chain at all. You are saying that the power supply can make a 1 straighter or a 0 exactly zero shape. In digital a 1 is a 1 and 0 is a 0. There is no taller or shorter one nor a fatter or thinner zero. Think about it.

So to the new wiim pro plus is not going have a USB output just better dac? The next model after it will include the usb out feature? Will the current pro be getting the peq equalizer or just the new pro plus?

my friend, i can think about it all you want but i will not find a solution to what my friends also confirmed. will it be group suggestion?

Just a better DAC and OPAMP.

I haven’t heard it said that the PEQ feature will only be available on the Pro Plus - in the past WiiM have said that it may be coming to the Mini as well as the Pro but with less bands than the Pro, say 4 rather than 10 for example, due to memory differences . Given the Pro and the Pro Plus will presumably have the same CPU and memory, I’d imagine there will be no difference between them when it comes to PEQ.

Thanks having one of those chemo memory days and just wanted to confirm the details.

Yes. Low quality PSU in conjunction with a poor device design can affect the analog carrier, which is a basis to any digital signal, to the levels above the acceptable threshold.
A noise leakage can happen when devices are electrically connected and not isolated. It can affect other devices in the audio chain.

Nothing unusual.

There is no analogue.
If there was electrical interference as a result of low grade / poor power supply then any effect would destroy a 1 or 0 completely and the stream simply would not play. Digital is absolute.

 

[d6jg]

I’m not saying that a poor power supply wouldn’t affect a DAC btw

Highly distorted signal eye patterns is all you need to get troubles with decoding analog carrier into correct digital values.

You've asked "Is there any possible argument that the power supply can make any difference to SQ?"
So it can easily affect SQ indirectly when other devices required to transform the data stream into the form of audible audio, are sensitive to SMPS units for example.

You misread my first post. I said streamer with no DAC ie no analogue in the flow at all until it reaches an external DAC.
Basically a computer which happens to have a coax/optical/USB out but no analogue so the signal path is entirely digital.

So I said it can affect the external DAC through the connection between the streamer and the DAC.

There is no "entirely digital" signal path as you do not send bits directly. There is an analog carrier which delivers a data. And that analog carrier can be affected by noise or distortions which will result in improper data retrieval.

Does this all come back to those who claim their WiiM device’s digital outputs sound better (I.e. more musical etc) with linear power supplies? I think I’m in the camp that would say how can it possibly sound different?

Wouldn’t that improper data retrieval manifest itself as audible clicks and pops rather than a change in musicality?
