But in the end, the DAM will convert DSD to PCM on order to convert it to analog. It has no other choice - it's an R-2R converter.

There are very few dac chips that manage to do DSD without first converting it to PCM, but that has very little to do with how the dac sounds in the end.
Interesting, thanks Dimdim

Are there any other connections on J10, or just the three listed?

Not for the sake of interacting with umanager if this is what you ask about - sorry I just saw that you have it working - so you are probably asking about something else?

No. Just wondered if it had another purpose.

Hi Soren,

I got the DAC1541 and my friend just past me a Singxer F-1 XMOS USB.

I would like to see the difference by connecting the Singxer usb to the DAC1541.

My best guess was the "J3" jumpers on the DAC board. May I obtain the information on it? Thanks.

I'm not sure what you're asking for, but if you want to try to connect an external USB to I2S interface then it's not possible nor needed, the dac1541 have its own perfect USB to I2S interface and it cannot be bypassed.

One question to users who are using Amanero (un-modified version) pairing with the Soekris DAC. What firmware on Amanero do you use to get the DSD playback? As I think I am using the CPLD_for_1080 + Firmware 1.096c3w2 and I get screeching noise when I play a DSD file either via Windows 10 PC + Foobar or Raspberry Pi + moOde OS. I have even tried different images like Volumio, Rune but its the same issue. Is the problem with the OS that I am using or the players (in case of Foobar) or the correct firmware on the Amanero?

Thanks

With the standard settings of the amanero board you have to enable DoP (DSD over PCM) for playback in the player(s) not "direct" DSD.

Yes correct I have that setting to "Yes" on the moOde OS.
