I own a Rega Saturn-R. IMHO it is a very good sounding CD player and the multi-input DAC works very well for everything I'v connected to it. That said.......
I have no idea what you are talking about regarding downloading a digital stick. I've connected an Apple laptop via USB, a Windows laptop via USB, a bluetooth receiver via both optical and coax cables and a Nuforce iDO iOS adapter via coax. I did not need to download anything to get any of these connections working.
What device(s) are you trying to use to stream to the Rega Saturn-R?
Since you bought a "demo", was there a dealer involved? If so, part of their "value add" should be assisting you with setting up your system. Can you leverage your dealer for assistance?
