@jazzman7 Just as you said, NAD C-658 does not have digital output. M50.2 is the only NAD unit that can feed coax digital to outboard DAC. None of the other NAD gear has the capability of sending BluOS stream (by MDC module or otherwise) to coax digital output. Even the M32, which does have digital coax output - will not output the BluOS stream to it's digital coax jack (yes it has coax output jack, and no it won't pass the BluOS stream - says so in the manual). This is extremely unfortunate that NAD built them like this, as it prevents using an upgraded DAC on all but the M50.2. Notice the new M10 and M33 integrateds don't even have digital coax outputs (older M32 has coax out, but it won't stream).
This small feature limitation caused me a lot of extra hassle, and it makes the Bluesound Node/2/2i the value option (even if you want all-in-one solution). Especially if, like me - you have speakers that require separate channels for each driver. BTW NAD M50.2 is very expensive relative to Node2i.
