I now have my QNAP core setup, and using with Roon. Really enjoying the enhanced features of Roon, such as the "radio" feature and all of the artist info, etc.
Thanks to all for the tips and providing the files (I think Roon now has them on their website, at least the QNAP core package). Anyway, one thing for others so that perhaps you can benefit from my learning curve:
Initially I had Roon on my laptop. As I listened, I was getting a lot of clicks pops and dropouts. Disabled everything I could software wise on the QNAP. Still noisy.
Then I decided I would try an old Mac Mini to run Roon, and use the laptop and iPads as remotes. Also moved the Mac Mini and connected to the same switch as the QNAP, and via ethernet connection, not wireless. Voila! Rock solid, and much better audio quality. Significant reduction in noise floor, and of course the obvious, no dropouts and extraneous network noise.
Going to tweak further, but amazing how much network architecture affects sound. I feel like I'm at least equal if not exceeding the Sooloos + MD600 setup previous to putting the QNAP in.
