Digital newbie

Hi all,

Could someone give me the 101 of digital today? I’m back in the hobby after a decade-ish hiatus and would like the basics of streamers v network transports v network players, etc and how Tidal/Qobuz/Roon play into it.  I've been on Aurender's and Lumin's website and I think I get the gist but wanted some clarificiation.  If there’s a specific thread for newbies like me, could you point me that way? Thanks!
