Hi jonnie,
here a bit more background information:
We had made somme additions to the linux kernel some months ago to support native DSD512 with our DACs on the Linux side.
It seems that the USB VID/PID numbers given in the SOtM list (0x2ab6 / 0x0004) come from these kernel patches.
A linux kernel having these patches applied can output native DSD to our DACs. So that is for the transmitting side.
On the receiving side:
A normal DAC8DSD has PID/VID = 0x2ab6 / 0x0001. So a normal DAC8DSD is not recognized by the Linux device as beeing native DSD 512 compatible. With this PID/VID combination a standard DAC8DSD will be recognized as DoP/DSD128 capable and this is what you have now.
To make native DSD512 from Linux work we need to install a new linux compatible firmware (with PID/VID = 0x2ab6/0x0004) on the DAC8DSD. This new firmware exists - but only in experimental form and we feel that it is currently not mature enough to be released to the public.
For anybody interested in experimenting with linux native DSD512 on DAC8DSD (and other DACs with Amanero USB reciver) some information can be found in this thread: https://github.com/lintweaker/xmos-native-dsd/issues/12. -> See the OE333 post from September 20th for hints on the DAC8DSD.
Regarding the Windows based bridge: A NUC should be fine for this purpose.
Best,
Larry
