From my personal experience, I can say that both the Aurender and the Antipodes are considerably better than the Mac mini solution from the perspectives of sound quality, control and ease of use.
The Aurender Conductor app works flawlessly, has an easy to use interface and a nice Tidal integration.
With the Antipodes, I use Roon as the control software. As indicated earlier in this thread, the Roon server software runs directly on the Antipodes. The Tidal integration and music metadata are absolutely amazing with Roon.
The sound quality of the Antipodes DX is much better than the N100H, but it’s close to triple the price.
Both the Aurender and Antipodes came with easy to follow directions and were problem free once set up. With each of these devices you do need a hardwired network connection whereas the Mac Mini can connect to a wireless network.
Would your local Aurender dealer be willing to loan you a unit for a home audition?
