I believe there is market for it, yes.
But people that go for the more refined sound do tend to want the DAC, the AMP, the SERVER, etc., separated so that it gets easier to upgrade components. For instance, I could upgrade to 'tomorrows' whatever new format changing my DAC but the analog output will be the same and I don't need to change the Amp.
Also, I could ensure a great CPU resampler and send it to the DAC of my choice. Or headphone amp. The fact that the Omnia does everything except the Amp is an interesting gamble. Lets see how people react to it.
For my tastes and setup, it has no use. I now have a RaspberryPi doing the bit perfect audio and resampling. And a DAC+Amp (all in one) that receives the inputs from the TV, a multi-room Airport Express and the RPi3. So I would move to separate DAC and Amp in the future, not into 'combining' more stuff into a single item and loosing versatility.
Also, I prefer the command on my phone, tablet, computer, or whatever I choose, rather than a touch screen on the item itself. So, in contrast with most other products in the NuPrime lineup, this is the least appealing to me.
I could be wrong, of course!
