How do I stream the NAXOS Music Library?

  I set up ROON today, along with Tidal, and I like that interface a lot. I'm running the ROON Core on my iMac 5k with TOSLINK into my Accuphase CD player's DAC. 

  I'm thinking about investing in a better DAC and would welcome some recommendations. I was looking at the Meitner MA 1 or the DAC2X, although it is quite a bit of scratch. How much money do I need to spend? LOL.

  One thing, I would like to do is to stream from the NAXOS music library

but it seems to only support streaming from a Flash player. Is there some way I can control the Flash streamer while it is running on my Mac? There is an iPhone app but that only seems to stream for playback on the iPhone. 
So, my thought is to buy a Mac mini and use the Duet app that mirrors a display to an iPad as an external display in order to be able to control the Flash streamer from NAXOS.

Information on the Duet program is here:
If Naxos streams like radio then Roon will handle it for you.

Meitner is excellent but Benchmark DAC3 could be an alternative.
  I don't know of any way to have Roon stream Naxos, and, as far as I can tell, Naxos does not stream like a radio station. You have to use a web player from the Naxos website to stream a CD that you have selected from a list. 

  I discovered Luna, which is a little dongle that will fit into my Mac Mini's display port and display the screen wirelessly on my iPad. Luna won't be available until around December. Once I have that, I'll be able to stream Naxos from my iPad.

  For now, I have to use a wireless keyboard and trackpad, along with a cheap 13.3" display from GeChic, to find CDs on Naxos and stream them to my DAC. 
Did did you ever buy a DAC?  You should be able to use AirPlay to stream the Naxos from your phone to the Mac Mini or to an AirPlay compatible DAC
Yes, I bought a DAC. I got a good deal on an Aqua Formula R2R DAC with USB input. I think it sounds great. The Aqua is recognized by Macs as a Core Audio device so it was plug and play.

As I explained above, I use a wireless keyboard, trackpad, and  small monitor to play from the Naxos website. I can’t wait for the Luna display dongle so I can control the Mac Mini from my iPad.
