Streamer vs. new mac mini for 2 channel system

Hi audio friends,

I LOVE the functionality of my mac mini with my 2 channel system: Exasound 62e DAC, Modwright ls100 pre, Coda continuum 8 power amp and Wilson Sabrina speakers.  Being able to navigate with mouse and keyboard from my listening position is infinitely better than using a tablet or some mickey mouse app with my phone.  

The issue is the mac mini.  Clearly this is not the best transport, however I want to use my 2 channel system for more than just streaming roon.  I listen to soundcloud a lot to learn about new music and when I watch tv I want to utilize the stereo for netflix, crave etc.  My Dac has only 1 usb in and obviously an optical + s/pdif, but the fidelity is just not as good with the other inputs.  

I almost pulled the trigger on a Lumin U1 mini, but again I do not see how this transport will improve fidelity, without limiting overall functionality.  How do I bring a new mac mini to a place where it can compete with a dedicated transport like the lumin, or is this even a reasonable suggestion?  

Looking to optimize the system in the most efficient way.
Confused - any suggestions would be much appreciated.

My MacMini 2012 model (with 4 cores) regularly crashed with ROON. Now I was also running Convolution filters at that time on ROON. So maybe my extra requirements was the cause of all the crashes. I switched to a noisier DELL mini computer but put that on in another room.

I also have Fibre Optical streaming to USB. So my computer noise does not get into my DACs.

You might consider using both sources in your system. I also have a DAC with only one input, however the Inday Digital audio Switcher allows you to switch between 4 different digital sources. In my case the Mac Mini, a Node 2i, and Rega CD player.

Running a Mac Mini as server vs Mac mini with top grade linear power supply is simply not remotely comparable. The issue with mm as server is it requires a lot of diy, not an out of the box solution. Audiophilelifesyle forum will point way to maximize mm as server, steep learning curve. Get it right and you have first rate server, no crashes, no issues. I can run dsd, way oversample, no Roon, Tidal, Qobuz, Synology NAS issues ever. Linear power supplies on ever single streaming component is where it gets really good.

@tvad-  You can try Keces P8 Linear Power supply or Uptone Audio JS-2 Linear Power Supply. Either one would work but the stock MacMini 2012 model needs an internal power supply upgrade to be able to use the 12V Linear Power Supply input. The Uptone Audio MacMini DC conversion kit would be an easy way to upgrade the internal power supply of a MaxMini 2012 model. Here is the link.

I don't know how to upgrade the internal power supply of a newer version of a MacMini but there are vendors in the market who could do that for you.
Thanks.
