technically speaking, with same hardware, it is possible to dump firmware form new device and flash it to the old device, even if the manufacturer does not release the new firmware.

New S.M.S.L. M300 SE 120$

idk ,i hope so
So mystery is solved - they've changed it
I hope, that new graphs are correct, I mean that new filters are correct.Hope that another mystery will find its solution - are there infamous microclicks in updated version. Hope not, I wish to buy m300se but I'am a little afraid..
Fixed one.
I just turned 70 and had involuntary hearing firmware updates installed over the last few years. Sadly, the new filters are not relevant for me.
I can only confirm how the DAC stopped for a second , about the volume of DAC more than 30 (max is 40) , not sure the exact number . At least I can tell volume ( 23/40 ) is safe.
has not been tested yet , I am using m300SE to pair 8020D.

omg , best news today.
I stuck at step 8 . "detecting the target MCU" , I pressed the input selection and waited like 3 mins , nothing change.
update : I change the bits per/s from 9600 to 4800, and it's working now.

ok, I got those. At first I thought it is the RS232 one. I'll just use the supplied cord and connect to my computer. Thank you.
Could you please give an info: has the firmware update helped to solve dac stopping issue?
So some more information about the sound quality of the M300Se after a successful SW update:
The microclicks are still there, but! with the setting Digital Filter 5 NOS there is no such thing!!!
At least I don't hear anymore.
That says the whole problem lies with the digital filter on chip.
I would argue that CS43198 and CS43131 sound best on Filter NOS anyway, I could see it on my other devices with the same chipset as well.
!In addition, I don't hear any microclicks with the setting: Fixed. This is very good news!
So, after the SW update, the M300SE just sounds fantastic, but don't forget that I modified my device, that makes a big plus for the sound. So with a good PSU the M300SE would be almost a reference DAC without any fun....
Next, regarding previous posts, DACs from AKM have never been really good except maybe AK4395 which is a cheap copy of CS DAC though... If you go into details go and you will see that.. Velvet Sound series is just fool.., this is not high-end, especially AK4499 absolutely wrong development.., you can hear that too..
The best of Delta Sigma DACs are CS/Crystal DACs (CS43122; CS4396,97,98; CS43198/131) and now also ESS DACs from HyperStream 4..

Tried every combination of speed settings, port 3 is listed, but on the Windows 10 & 11 this program won't update. I can't understand what it's saying, since it's not translated. I've never seen such a poor quality firmware updater. I've built computers for 35 years and buy $6,000 a month in audio equipment, and have flashed a LOT of things. This app looks like it was written by a student in the 1990's. I've got a SU-8s and DO200 MKII with this M300SE, and suddenly I don't care if I ever buy another SMSL DAC ever again. This is the 2023 way to flash firmware, with a program that has potential to brick a device? Why are they selling in the U.S. market with that's not even in English using COM ports? If it hadn't failed on both computers running two different OS's I would have given them a pass.
On my Win 11 computer, it did not update until I switched to the USB cable that came in the box. The one I had been using worked fine for transmitting audio, but not for updating. It did say to use the original cable in the instructions. Single cable, connected to the upper USB port.
I noticed that when I had the correct cable attached and first powered on, the associated Com port appears in the task manager.
The instruction are correct, and I think nearly all the clicks are illustrated, even if the buttons are not in English.

The microclicks problem lies on the class mode AB or H, it is written in the cirrus logic datasheet, and it is shown in the RAA article you linked. If you can't hear it with the NOS filter for some strange reasons, an audio measurement might help.
I don't know why SMLS does not state about that whereas many forumers want to know. Ibasso makes no secret with their DCO4pro about that.

Interesting. Can you point to where Ibasso references this issue?
