Music Server offering a significant upgrade over a Mac Mini?

[savjam]

I was using a Mac book pro feeding a Ultrarendu outputting into a Bel Canto Ref Link.  While the sound was good I felt it could improved upon so I decided to experiment.    I bought a base model Mac Mini (4GB of RAM/none SSD) and Uptone Audio’s MMK and JS-2 power supply.  My music player is Roon with my music mainly sourced from Tidal.  The Ultrarendu’s Ethernet is connected directly to the Mini via a network bridge.  Doing so bypasses my router for an improvement is sound quality.  I realized a big step up in sound overall compared to the Mac Book Pro with the biggest improvements in naturalness and dynamics.  So, yes, improving the source makes a difference no matter how good your down stream components are.
