Does SMSL actually support DSD512?

[chasfs]

I have an SU-9 and SU-10 connected to various Windows PCs and Foobar2000. I’ve been trying to use SACD_input and can get up to DSD256. To my ears the imaging is improved with DSD256. Both of these DACs claim to support DSD512 but they top out at DSD256.

Has anyone been able to get DSD512 to work?

possible that SACD_input is using DoP and the DAC can only play DSD512 via Native.

Here's a short step-by-step for native DSD in foobar:

For this to work, you need to install the SMSL driver.

Thank you very much!

l got both the SU-9 and SU-10 to play DSD512
On the SU-9 I was listening to Maggie Sansone dulcimer and heard some clicks that shouldn’t have been there. I replayed the beginning of the same track several times. More than half the time I heard clicks. I tried again at DSD256 and got similar results - clicks that shouldn’t be there. I switched back to unprocessed PCM and have heard zero unexpected clicks.

Other than the clicks I have trouble hearing a difference between PCM 44.1 and DSD256 or 512 on the SU-9.

That's the magic of the Nyquist–Shannon sampling theorem. Even 44.1kHz is enough for complete transparency to the human ear.
