Yes. Yes however I believe it is converted to PCM first.
The same USB card is also used in Dac202.
The FPGA chip in the middle is the $20 Xilinx Spartan XC3S250E.
From the INT204 brochure:
The INT204 USB/DSD Interface is a USB to AES/EBU and S/PDIF interface which can also do DSD to PCM conversion.
It thus allows to play back DSD files via any standard PCM D/A Converter.
Note, the conversion of DSD signals to PCM before doing the D/A Conversion has an advantage over a źnative╗ DSD D/A
Converter in that the analog output filter after the PCM D/A stage is of lower order and hence sonically transparent
compared to the analog filter which is necessary in a źnative╗ DSD D/A Converter.
I guess the new gear from Weiss measure excellent as Weiss is well-known for.
