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.

@fuzztone, McGowan uses a Mac Mini until his long promised streamer comes to market.
@unsound.
That’s what I said, Apple. He stresses that the only thing that makes it tolerable is BitPerfect.

BTW I also retired my Synology, a pita.
I have relegated my Synology and QNAP nas boxes to backup duty.  Roon running on a Roon Nuc with ssd's now and a complete copy in Dropbox (although I'm teetering at the 2tb Dropbox limit and last I looked the next size up was a lot more per month as a 'business' account.)
Thank you everyone for your responses.   I think I'm going to get the lumin u1 mini for streaming Roon and find some computer alternative for streaming YouTube, SoundCloud and Netflix etc.  

Does anyone know if I can access the lumin through my laptop? Or does it have to be a tablet, phone etc?

The latter part of my question is still mysterious to me.   Is there a mac option that allows me to use an optical out so I can switch from USB to optical and at least get a half ass signal to my Dac? 

Going full digital is not as convenient as I imagined.
