Thanks for clarificationThe DSD problem is due to MAC system limitations.

So based on the DSD quality, i have to set cut-off frequency manually on the D300? What is it for, why do we need to do that?The programmer of HQPlayer measured the D300 with DSD as well and suggests the cut-off frequency of 13khz with DSD512. That gives you 104khz.
And with DSD256 the cutoff frequency should set to 26khz.

I've been curious that feature on the D300 but don't know how to look up, can you please explain more or share some key words or articles about it?
Thanks
my very new d300 has no problem with coax and even bt input but when used with a MacBook connected with a usb cable stop playback after few seconds? any help?.Very likable anyway, reminds the burr brown cpm 63 chipMine is different but has a clicking sound using Audiolab streamer as a transport when playing HD 48khz + from AMHD but works fine with other sources. I now use WiiM as a transport without issues. Likely different issues but wanted to share. cheers
Does this imply that more DACs with the Rohm chip are coming?This is our first dac on Rohm Chip. D300 sounds more like playing vinyl, the felling more analogSMSL D300 Decoder DAC ROHM BD34301EKV Bluetooth 5.0

Because they have a sale ?Does this imply that more DACs with the Rohm chip are coming?
Not really, but any reason would be fine.Because they have a sale ?
It would certainly be nice, ROHM Chips have a direct DSD mode like AKM chips.
I went through this whole thread due to the fact I had serious interest in this dac. And also recently purchased the A300 to pair with it. Currently using the D-6.
Now…I’m on the fence about the D300 with all the reported issues. Is there anyone here who has had trouble free units from day one to present? Cheers
Thanks for the reply. I also plan to use USB(from PC/Tidal and Foobar)but also OPT from TV. Most likely RCA to A300. The A300 will be running the Elac UBR 62’s.Here. Connected to a headphone amp (XLR). And only input i use is USB from a raspberry pi.

All the qualities I’m hearing bout the Rohm chip and the fact that I actually live in Kyoto(where it’s made) have me interested. I also play concerts at the Rohm Theater and am a fan of their work towards providing scholarships to young artists.
Actually this ROHM chip only operates in DSD Direct mode - there is no other mode, unlike AKMIt would certainly be nice, ROHM Chips have a direct DSD mode like AKM chips.
I tried to rewrite the D300 MCU firmware update work in an easy-to-understand manner.
Prepare for update
Unzip the downloaded update file "SMSL D300_MCU_FW 221012".
”IAP_D300_MM32_1v1.hex” in the unzipped folder ”SMSL D300_MCU_FW 221012” is the configuration file to be specified in the update work.
Furthermore, unzip "ISP_PC_EN.zip" in the folder.
"ispV2.4.exe" in the unzipped folder is the update tool.
Start update
Turn off the power switch on the back of the D300 before starting the update process.
Remove the USB cable connecting the D300 and the PC.
Click "ispV2.4.exe" to launch the update tool.
Click "File" in the upper left corner of the screen, then click "Open".
On the screen to specify the installation file, specify "IAP_D300_MM32_1v1.hex" in the unzipped folder and click "Open" at the bottom right.
Wait 30 seconds for the update tool to prepare the files for deployment. At this time, there is no change on the PC screen.
After 30 seconds, connect D300 and PC with USB cable.
Hold down the FN button and turn on the power switch on the back of the D300. Release the FN button after 5 seconds.
At this time, the screen of D300 remains off and there is no change.
"Disconnect" is displayed at the bottom left of the PC screen.
If the D300 normal screen is displayed by this operation, redo the operation.
After 30 seconds have passed, click the "handshake icon" in the upper right corner of the PC screen.
Then "Disconnect" at the bottom left of the screen will change to "Connect".
Click “Start Program” displayed near the center left of the screen.
The firmware update process will begin and you will see flowing text on the right side of the screen indicating the processing steps.
When the update is finished, "Complete" is displayed and the screen of D300 lights up and it becomes normal operation.
This completes the update work.
I don't have windows. I never updated my D300. I have none of the issues people seem to have since I use Roon and Raspberry pi4Hello ? lol
Installing the SMSL D300 FW 221012 turns your DAC into a "speaker killer".Has anybody here been able to successful do the February 2023 firmware update? Both MCU and USB updates?
No brickings of the device?
Can anyone share recommended instructions for how to update ?
