I usually have Foobar configured to play DSD files native on the Mytek. Well, that is jolly good. But like many of you, I have signal strength issue with a lot of PCM files. The Mytek has to be attenuated to play properly. I came to s stage where the Mytek is used almost exclusively for DSD files only.
Recently, I started a dual-PC project and feed the Mytek using JPLAYmini and kernel streaming as the interface. The result is very pleasing. I have no signal strength issues. I can all other PCM files on the Mytek, beautifully!
May be this is "old news". I am posting just in case you haven't discovered.
Cheers.
