I think you may missing the point of why this amp is liked so much here. It's a one box solution, although that box is quite big and heavy. The integrated amp is very good, the phono stage is good and the DAC is very good, despite the DAC chip being a little dated.
No reason why the Auralic Aries mini could not be plugged into the DAC of the amp.
In fact, having just acquired one of these, I am thinking of a similar set up as well
