WiiM Mini Streamer

[MrBrad]

More evidence of bit perfect performance: as long as digital volume is 100%, DTS encoding successfully passes through the WiiM Mini.

 

[morillon]

actually, can it be bit perfect if there is an early """"clipping""" problem in toslink? eq-off mode

;-)

I do not know too much about DTS. How is it processed by WiiM? Is the file decoded to the DTS raw data instead of PCM and then passed through?

Same as the MQA discussion. DSD over PCM is another.

WiiM Mini simply passes through.

If any bits get fiddled with, DTS, MQA and DSD over PCM (DoP) will fail at the DAC.

I mentioned DTS here yesterday also.

And my question is still open - how DTS or MQA decoder will react to just one bit manipulation?

If this kind of data is sent untouched by WiiM by default it's a different scenario to the one when WiiM decodes data to PCM format itself.

Please look at this discussion:

Shenzhenaudio Topping EX5 Review (DAC and Headphone Amplifier)

I put the EX5 in a measurement loop using REW on my PC, same way I've measured other equipment. I played frequency sweeps at sampling rates from 44.1 through 192 kHz. The EX5 frequency response always extends to half the sampling rate (Nyquist). For example, play a 96 kHz sweep and the EX5...

Similar behavior has been mentioned already.

Thanks, I could have sworn I didn't have a "reply" button. I can see it now.

Do you remember the bug when WiiM was adding unexpected fade effect instead of being pure gapless? Do you think it was a bit perfect behavior?

Yes I remember. Clearly not bit perfect behaviour in their initial attempt at gapless.

Their release note on their website hasn’t been updated.

That is why I still drill down on the topic. I would like to get a kind of real life proof of being bit-perfect / imperfect. I'm also trying to understand the basis of some statements I can see that WiiM sounds worse than X with the same DAC connected.

I will report back in a few weeks when I'm not so busy and do the test.

So we can finally close this chapter and get back to @Smartplug's daily crying for the WiiM Pro appearance on Amazon

You may or may not believe it but those high resolution music file sound less exciting to my ear and 44.1 sound better to my ear.

Lol, you surely knows how to pick a topic. First, it was rumored to be early October now got push back end of November or early December. Release the pro, I’m sure it will get the same as mini an update every couple of week. Take my money release it now! I buy 2 and donate the other to music1969!

We are going off topic of WiiM Mini but it is well known that much hi-res often just has a lot of high frequency garbage, especially anything above 30kHz.

There are some really well done classical and jazz releases that have 'clean' spectrogram but a lot of the popular/rock hi-res out has junk/noise above 22/24kHz.

I've analysed a lot of stuff on Apple and Amazon UHD and Qobuz and wished I didn't lol - it's not pretty !

When high resolution became a mainstream streaming services, I was thinking like going to dvd to blu ray and give you a wow factor but damn it was the opposite. I have tried many 96/192 but none excite my ear. I preferred just listening 44.1. That just me maybe others has different take on this.

I do not hear the difference between true hires song and it's downsampled to CD standards version.

BTW, did you ever try this kind of tests, guys?

Human ear can hear up to 20khz on early age but deteriorate when aging. So, streaming company push this services to charge more making us to believe it sound better. Take for instance John Lennon “Imagine” sound great on 44.1 that I have on CD but as soon I choose 96khz it just made the sound less exciting. Spotify just releasing hifi without high res I’m ok with that since I have tried all of them high res on my ear don’t sound great.

I think a more important thing than the sample rate is the audio bit rate. 24-bit audio file could be noticeable if it is originally recorded in this way.

funny I point out that there seem to be strong clipping problems on toslink same mode no-eq
(approved from -1db in 48k24db for example, same as 96k etc)...
which is not without consequences...far from...
(wiim seems not to ignore it but the fix doesn't seem to be there yet...)
but we continue to talk about the good old subjects high resolution or not etc.
amazing...
;-)
anyone to do these checks? refute?
ccif smpe
wiim should be able to adjust this quite easily
this problem is quite recent

I have both stream and wiim but like sound of wiim using the same dac. As soon pro reach amazon I will purchase it immediately. Early December cant come any sooner!
