Given the current level of hassle with Foobar, if I was the OP I would just shell out for Audirvana, which in my past experience had pretty good support (the OP may want to investigate this during the trial period) or since this is a second system, bite the bullet for a relatively inexpensive streamer that does DSD, such as the iFi product. If Foobar is this difficult to setup, consider what might happen down the road. A software update of your computer OS might suddenly cause a malfunction, and then if you are back to square one you would like to be dealing with a product that was easier from the get go
Playing DSD files
I have a small but DSD-capable DAC (Topping E30ii), and many DSD files on my hard disk. I am trying Audirvana Origin (one month free trial). It is able to play my DSD files, and the sound is good. However, before I buy it, I would like to test Foobar2000, with DSD components / plugins, maybe the sound is equally good. Yet I cannot get it to work. I’ve installed foo-component for dsd and sacd, but no sound, or even error message: unrecognized format, trying to play my .dff files. Anyone knows a workaround? With Foobar, my DAC display shows PCM (up to 706), it does not show (correct) DSD, like it does with Audirvana.
