Lol, that was supposed to be in the Tenet thread.So you watched a movie with a DAC... please, tell me more.

Too funny

You wanna correct your mistakes right?
Since this 3rd harmonic distortion issue is common on almost all SMSL DACs per the comments here...I feel @amirm may consider downgrading or removing SMSL DACs from ASR top DACs list. It's the least we can do to save new ASR members from thia SMSL trap!They haven't even released an official statement about this issue.
I have some thing to ask and something to share on what's going on in my setup. I bought two units of the SU-9 from HiFiGo in the last months. The return period has expired and I honestly thought at the time that I was upgrading from M500 to SU-9 and that it was worth it. Now I want to understand what the issue being discussed means for me as well as other plan users of the SU-9? Is my DAC garbage? Were the measurements reported in Amir's review not repeatable in actual home setups? Basically should I get rid of the SU-9 and buy some other DAC and would that be audibly superior due to the faults in SU-9, if yes...in what way? I feel I am defrauded yet again by SMSL and all I want now is to assess the extent of damage. Finally what's the solution available to me or other users to correct the situation?
Now that sharing part. I have hooked up my SU-9 to a NuPrime A300 D Class amp (temporarily) untill my NAD C298 arrives and am running KEF R7s with it. Below is the REW measurement of pink noise from my system. I notice a very very noticeable clockwise shift in frequency response. Any link to the issue being discussed here? Any possible reasons why this is the case?

To be fair to SMSL, I think the issue only affects the SU-9 and M500 DACs (i.e. the DACs based on the ES9038PRO chipset). There are quite a few SMSL DACs that are unaffected.Since this 3rd harmonic distortion issue is common on almost all SMSL DACs per the comments here...I feel @amirm may consider downgrading or removing SMSL DACs from ASR top DACs list.

Perhaps, but doesn’t change what I said; namely, that the third-order harmonic issue only appears to affect the SU-9 and M500. @Shoaibexpert suggested it affected all of SMSL’s DACs.SMSL started as a promising brand but QC has taken a nose dive. Recent products have been beset with issues such as those mentioned above as well the SA400 tested recently here which had coil whine.
Not to mention FR limited to 20K making Hi Res impossible as noted in Amir's review...tested recently here which had coil whine.
Actually no. They have always been the same.SMSL started as a promising brand but QC has taken a nose dive. Recent products have been beset with issues such as those mentioned above as well the SA400 tested recently here which had coil whine.
This is brilliant and the only reasonable reaction to reproduce on M500 and update your recommendation (maybe also soon for SU9?). Smsl must understand that building overall pretty good products is not enough if they provide NO customer service and no bugfixing at all.FYI I confirmed this problem with SMSL M500 and updated that review with new measurements and withdrawn my recommendation of it. I have also sent a strong message to SMSL to respond to this issue or it will seriously impact any future recommendations of their products.
I also ran the test on the last two Topping DACs and there is NOT a problem there. I will perform spot checks on this moving forward. I don't think it is a common enough problem to report on it on every DAC.
It's a firmware/software setting oversight for the ES9038PRO operating in 2 channel, not a hardware issue... the problem is solved, however SMSL/Shenzhenaudio need to provide a reasonable update path for current owners.I suppose 1 or 2 decoupling cap in proper place would solve the issue
As an active competitor to SMSL, and with past products that also have various issues, I would suggest you stay out of this thread as a professional courtesy.Actually no. They have always been the same.

I mean I would imagine the retailers such as Shenzhen or HiFiGo (where I bought my 2 units of SU-9 from) wouldn't wanna commit resources to solve manufacturing defects from SMSL!
