PS Direct Stream Vs. Lumin X 1 Sound quality difference?

Aloha!
Arriving late to the discussion....a very good and informative one I must say!
Hope this is not a hijack or that it should be a separate post.
So up until a few weeks ago I was on course to buy a U1 streamer to run into my Luxman D-10X DAC section.
Well those plans got a bit derailed and I am now putting CD playback on a back burner as far as upgrading right now. No more D-10X at least for now.
So my thought goes toward the X1. And at this point it is really the only Streamer DAC I am considering. So that part is easy :-)
Question is...I use Roon (sometimes reluctantly) and wish to also use the Lumin app. I stream Qobuz and have a reasonable sized library of Hi-res and CD quality stuff.
BTW....my modem and router are next to the hifi rack.
What do I use to get al this stuff to the X1? A NUC, Nucleus, NAS?
As you can tell, I am a complete digital idiot!
I figured I ask the easy stuff first before digging into ethernet, switches etc...hahaha.
Mahalo for your help.

mauidj,
I will do my best, I have an 8TB external hardrive plugged into the usb port that has all my music on it and I just use the Lumin app.
I stream Qobuz daily but the X1 is Roon capable.
BTW, they just added 40 high quality radio stations.

So all of this is possible.

Thanks ozzy. So if I dont have a huge need for Roon's interface, multi room stuff or DSP tricks I would not need any computer to play my music and Qobuz streams? All done within the Lumin app. I have to think it would sound better than having a computer in the way...no? Like I said...I'm a digital idiot!

No extra computer needed. You will need a iPad or a similar device to select songs.
BTW, I also go straight to my mono block amps. (no preamp).

Now thats what I like to hear. I was getting a bit intimidated by all the "audiophile" switches, NUC's with pricey LPS's, expensive cables.....
