My Stream plays all sample rates including DSD. I use JRiver. It was not easy to get it configured, but once it was set up properly the sound quality is excellent. Adding an inexpensive d-link dgs-105 switch boosted the sound quality even more.
How did you get JRiver configured properly. Is there a guide somewhere that you used?
I'm curious how the switch you mention improved sound quality. Did it replace a switch of lesser quality that caused jitter or noise?
