NAD M66

I am interested in the new NAD M66.  I use Bluesound Nodes in multiple zones in my home and would love to find a BluOS compatible "higher end" streamer for my main system.

Does anyone know what streamer NAD uses in the M66 is it more higher end than the standalone CS1 endpoint streamer or did they just plug the CS1 into the M66?

I looked on the NAD website and could not figure out how to contact them.
