I would keep the Innuos and get a better DAC.
I own the Innuos (Mini and Zen 3), and I find them very capable. Albeit, I use Roon and not the Sense app, so I don't know what you are dealing with in that case.
As far as DAC's go, the Ayre QB-9 Twenty, would be a great choice (I use it). And, can be had for less than $2K used.
My main reason for going with separates is that DAC technology is constantly changing/improving. By having separates, you'll be able to keep pace with those changes.
As far as the Innuos goes, I would look for the Phoenix units. The USB really improves sound quality, and the Ethernet one (which I just demoed today at Audioconnection) really, really cleans up the signal, as well. Yup, spend more money, but if you want to maximize what you own, these are great add-ons.
Lastly, if you want to just have an All-In-One, get the Aurilic G.1.1.
For $3.5K you get everything you need to stream, and get outstanding sound.
I listened to this today, as well, and was wowed.
