Quick Question or two for NDX/Hugo Users...

I'm contemplating the addition of a Chord Hugo to my system and am wondering about some of the finer points as follows. Can the NDX route its digital inputs through its digital output? I use UPNP, Spotify and iRadio on the NDX plus feed a TV to it via optical cable and I'm wondering if when using an external DAC, these inputs can be fed to the DAC from the NDX digital out, ie. keeping all digital switching at NDX with none at external DAC. The idea of using an NDX sans its own DAC seems a bit bonkers, but I like the Naim interface and read that it works very well as a transport only so am a bit torn on whether it would be justifiable to keep one for this only. All very hypothetical at this stage anyway so no stress. 

Second question is whether there is any reason it is not possible to have the NDX connected to NAC202 via its analogue output at the same time it is connected to a Hugo via digital out with the Hugo then connected to NAC202 in turn. The idea here being that it would be nice to have the option of taking the Hugo on the road so to speak for headphone duties but still have a functioning main system. I imagine this would require switching between NDX digital/analogue out as I assume it is not possible to enable both simultaneously. Thanks in advance!
