I personally own a SU-9, the question is how can I get such plug like you have received. One end looks like a HDMI plug and what is the other end?I think this operation is very simple for SU9 (the operation instructions are also completed --- it is currently in Chinese, and it is not very clear. I will make comments). The question now is how they provide services for the units sold. I will continue to follow up on this.
Compared to SU9, I am more worried about M500...
I believe that there needs to be discussion within SMSL on how to provide upgrade tools and guidance.I personally own a SU-9, the question is how can I get such plug like you have received. One end looks like a HDMI plug and what is the other end?
If SMSL publish how the pins are soldered, may be some of us are able to solder it for oneself.
Yes that sound more reasonable, many thanks again.I believe that there needs to be discussion within SMSL on how to provide upgrade tools and guidance.
I just checked the multitones chart made by @amirm but I couldn't recognize that 5db difference between 1khz and 2khz. Prof. Wolf, is it possible that the SINAD by multitones test after this fix is worse than with former firmware?
Do you mind to make a multitones test with new firmware?
Lesson learned thank you @liu, I didn't know it.Has nothing to do with multitone.
Chinese DACs are optimized for 1khz SINAD in order to sit on top of the SINAD chart on this forum.
optimizing for 1khz is easy --- one can tune the thd compensation for 1khz and make 2nd and 3rd harmonics really low.
However, it may affect harmonics for other frequencies.
In this case, 2khz fft clearly shows the second harmonic is way higher than that of the 1khz.
Another reason that people should read amirm's review in a critical way.

At least it is a possibility, unlike most others. Given that there has been good support M8 firmware update.I believe that there needs to be discussion within SMSL on how to provide upgrade tools and guidance.
What's with the "fever" thing, why is that translation not sorted out? I mean it's years now, that I've been seeing it. I think I read an explanation but I can't remember. fever grade...of course Google is no help. ...High fidelity grade? Low noise grade? ...If I find the Chinese text, then I could see what translate.google does. ...
just means hifi"fever grade"
@WolfX-700 , what is the right translation with the "fever grade" thing? I just came here from post on D1SE DAC https://www.audiosciencereview.com/forum/index.php?threads/smsl-d1se-balanced-es9038pro.23514/ and Shenzhen Audio page...

Nah. It means Audiofool grade!just means hifi
LOL!Nah. It means Audiofool grade!

M400?Hey, this standpoint may be TOTALLY biased.
If optimization of distortion at one specific frequency is at the cost of sacrificing performance at other frequencies. twists can be easily observed in a 20-20KHZ THD + N vs Freq graph as @WolfX-700 said. However it's hard to find this kind of measurements of the top DACs, isn't it?
