I've never used Roon and don't intend to either because it has the potential to interfere with the original recordings.
I use an Aurender N20 with the Conductor App via Android, however Aurender do tend to prefer Apple, but Conductor doesn't interfere with the original sound in any way.
I have over 3000 Cds, SACDs, DVD-A's and BLU-RAYS stored on my Aurender SSD drives. When you have that amount of storage the last thing you want is pics because it'll take you forever to scroll through them.
Conductor has an option called Folder which gives a DOS like list of everything you've got.
Pics are for Noobs, but they're there if you need them.
If you can't stretch to the N20 the N200 is a fine machine.
