I'll leave that as an exercise for someone else. I'm perfectly satisfied that the WiiM Mini is bit-perfect.
I would say it's an approach similar to the case when someone refuses to do a blind test because he knows that he can hear the difference.
But I can understand you are not curious about the result of a test I suggested, so ok and nvm.

Not at all the same. RME provides files to test for bit transparency. They work.

Unlike many "high end" providers, RME doesn't engage in marketing shenanigans. They are an engineering-driven company, as @amirm's tests of their products shows.

From RME's website:

Ever wondered whether your OS, its core drivers, the player software, the interface driver and the interface format all work with full bit accuracy? A bit transparency test can give an answer. RME provides several test files (wav) as free download. These wav files can be easily played on Windows, Mac and Linux computers. Playing them back with bit accuracy will issue a message on the ADI-2 Pro's display, saying 'Bit Test – 16 Bit, 24 or 32 Bit passed', according to the used file and available resolution. There is no need to set anything at the unit.

I take them at their word.

Have you ever benchmarked anything? RME test has some similarities to synthetic tests IMO. I prefer real world tests whenever possible as more transparent.

Does it really matter? I’m quite satisfied with 192/24 streaming from Amazon when available

It's not about personal satisfaction. I'm fully satisfied with 96kHz audio sent from Mini to my miniDSP for acoustic correction.

AFAIK sinad is an abbreviation to "signal to noise and distortion ratio". Can you explain how it can indicate if player alters some data in the decoding process?
Yes, it was actually dynamic range that was measured since there is no harmonic distortion in the digital domain. I called it SINAD since this is the name Amir has been using in his APx template:

I really want to love this thing… but constant dropouts and after the latest update 24/192 streaming on Amazon which worked fine before results in a loud white noise/screeching sound every-time a 24/192 track comes up in a playlist.

I'm streaming 24/192k on Amazon Music UHD. Works fine for me.

Faulty optical cable? Could be a faulty WiiM Mini itself (TOSlink interface)?

But can't be a firmware bug otherwise I would have the same problem - I don't.

I'm on build 20221017

wiim was part of saturation problems in eq mode etc that they would have settled ...
seemed to me that the sound was really bad for quite a while
I wanted to take a closer look...
for those a little equipped
, Could you verify?

I find a saturation in non-eq mode on a simple 1khz 4824 etc.
in my case, optic num seem " kaput" ;-) ...( for example
s observed even more easily on compressed radios etc with a flux at almost 0db constant
etc, in situations far from 0db, this will not notice )
(same manipulation with a chromecast but no worries there)
last firmware and wiim home android

fast examples 1k 4824 0dbfs same condition, to strike the spirits ;-)

I find a saturation in non-eq mode of -1db on a simple 1khz etc.

I'm not sure if I understand it correctly. Left chart was for fixed volume at 0 dB, and right one at -1 dB?

BTW, I've seen once that Mini was reporting Volume = 0.99 instead of 1 when fixed volume had been enabled.

no
sames conditions optic spdif...
the essence of my remarks, I especially hope that some will realize a little the same observations to validate my fast observation???

the clipping problem is still there.. that's all... in no eq mode too (since ? in middle of september seem ok like my first picture)
it is somewhere more important than 192k and co

in my case deezer does not really work
I still had some radios
some heavily dynamic compressed radios "fun " became quite
"inaudible"
I bring out the chromecast "for everything"

I'm a new member here. Hi all.

About a month ago I bought a WiiM Mini and am very pleased with it.

On Friday, I replaced my old DAC (Cambridge Audio DACMagic 100) with a Topping EX5 DAC/headphone amp.

With the DACMagic connected to the WiiM Mini the DAC displayed 24bit 192kHz on certain songs from Amazon Music USD. With the Topping, these are displayed at 16 bit 44.1kHz, although the WiiM app shows them as 24 bit 192kHz.

The Topping specs say the optical input is PCM 44.1-192kHz 16-24 bit so it should play at the highest resolution.

If I connect my laptop to the Topping via USB the same songs display at 192kHz.

What am I doing wrong?

You will always see max sampling rate on DAC connected to the laptop via USB when you play from Amazon Music app because the app upsamples songs to the rate set in the DAC driver properties.
Regarding WiiM, what happens when you limit toslink to 96 kHz in WiiM Home app settings?

No issues with Amazon 192/24 for me. Change optical cable and check Wi-Fi

When I set the toslink limit to 192kHz 24 bit in the WiiM app I can hear the test music and the app displays a message saying the output is 192kHz 24 bit. However the Topping EX5 still displays 44.1kHz.
The same happens when I change the toslink limit to 96kHz 24 bit.

Very strange. Perhaps it is the Topping display on optical input that is faulty.

PS how do I quote previous posts?
