It is the Schiit Loki DAC. I did follow Schiit's directions for the Loki the best I could. Their website was somewhat outdated from MC20. I do convert PCM on the fly as well as use my Musical Fidelity from time to time. Both DACs are connected via USB and all drivers are up to date.
don't know what you mean about their website is outdated, but does this happen with DSD, PCM or both. I'd guess it is only when playing PCM music?
They say you can do this on the fly from JRiver, but it is still a DSD Dac only -- a module made to operate as an addon to their Bifrost and Gugnir Dacs IMO. (or any other DAC). But the way you describe it it does sound like it is PC or USB related.
I would try to two things:
- first make sure that in your windows sound config that NO system sounds is checked in the sound profile - the click could be the system over the USB. Schitt mentions this so you probably have already done this.
- try to run your PCM stuff through the Musical Fidelity DAC and then connect to the Loki; push the button on the front. Any clicks?
If you are using optical or coax, they say that using USB should remove this. If there are still clicks and you are using USB, its probably a USB issue on the PC side, and I would try to get a powered USB hub.
Or you could set up two zones to switch automatically of course, shunting the DSD to the Loki and PCM through the M.A.
