Is it confirmed on which of their competitors specifically do not do this? Qobuz? Or is it possible that they all do?

Qobuz maintains the advertised sampling rate. Apple Music may issue a HiRes album (say 96kHz) - some tracks are at the correct sampling rate and others are transcoded to 44.1kHz. I spent weeks with 4 levels of support on this; they know it but are not fixing it.

What makes you believe WiiM devices aren’t bit perfect? I recall @onlyoneme testing using their RME DAC’s bit perfect feature to pass a test file through the WiiM and what was output was a bit perfect copy of what was input.

i thought the adoration of the bit perfect goddess is history anyway?

of coursePerhaps, but that doesn’t mean it doesn’t exist
1 - play it from Ultra via the WHA Qobuz app
2 - Play it via the Qobuz app on an iPad
3 - Play it via Audirvana or Diretta or Roon
They all sound different.
As I said, I'm not interested in controversies. I know what I hear. Others do and still others do not.
Edit: see post below.

if i ignorant layman who only has to depend on his nature given ears would not hear a difference with them i would not pay a lousy cent for roon. but audio, ergo solvo!

Configured correctly, bit-perfect is bit-perfect. This was tested not be imperfect ears but by perfect electronics per:
If the exact same 1s and 0s that went into the optical input of the WiiM come back out any of the digital outputs of the WiiM when configured correctly, that means that it is perfectly capable of bit-perfect processing.
What's also perfectly capable is humans using things the wrong way.
I'm not denying that you heard different. I'm saying something was probably not configured right. Lock volume. Zero PEQ. Zero room correction. Zero DSP (bass management/crossovers/filtering). Zero sample rate or bit depth locking. This should and can allow bit-perfect from the WiiM. It's also a lot to configure and easy for anyone to miss any one step and considering ALL of those steps must be followed, I'm sure 80% of people aiming for bit-perfect from the WiiM streamers misses their bullseye.
And FYI I also am an Audirvana user for my personal library. I get what you're saying about the sound. I really do. I'm just saying that I disagree with you on it being impossible with the WiiM--it's just very difficult and annoying.

Some time ago wiim said they'e add effectively a one-press option to enable bit perfect, i.e. reset /turn off all settings that can affect this.
Not seen it yet.

Yeah true, but lacking that some of us have long known what settings to set or defeat to achieve WiiM ‘bit perfect’. My Pro and Ultra have those settings correctly applied since day one.

Looks correct to me. The only real and proper test is to hook up the appropriate type of equipment to your system and perform the right test. Either it’s bit-perfect or it’s not, and that is a test whose results have no chance for misinterpretation given either it’s exactly bit-perfect or it isn’t.
Fair to say we won’t know unless someone sends you such gear. It’s not realistic to expect you to pay for something like that.

As I’ve mentioned, @onlyoneme did that using their RME DAC some time ago, and their word’s good enough for me

I feel the same way you do, but technically that is only 99% of the way there. To truly get 100% certainty, we’d have to test Adias’ system.As I’ve mentioned, @onlyoneme did that using their RME DAC some time ago, and their word’s good enough for me

You must realize some of us have been around here a long while. I am very familiar with onlyoneme’s measurements (good man and good work). I know of him perhaps more so than most
. Sure the stream is bit perfect. But there’s more to it re SQ. Let’s agree to stop here, OK! If you are interested we can continue offline.

I have no issue with you mentioning other potential variables (power supply quality, cable/connector quality, analog circuit quality, etc.), as once you get into the analog domain, I can agree that as yet there are some things that cannot be measured or explained.You must realize some of us have been around here a long while. I am very familiar with onlyoneme’s measurements (good man and good work). I know of him perhaps more so than most
But bit-perfect is bit-perfect.
You can even explain that there is poor clocking or jitter, I’m okay with that (even if it is arguable).
But bit-perfect is bit-perfect.
Or it’s not.
And that’s the topic at hand.
