Please don’t be offended, but keep your Mac mini because your price point isn’t going to get you significantly better anything. Get a digital digital converter instead and a little bit better usb cable. To significantly beat my PC with a digital to digital converter and 2 dh labs mirage usb cables I had to go to a $8000 innuous pulsar and a $1075 Crystal cable usb.
just try a
Singxer SU-6 d2d box first!
