I finally got around to looking into how to get my personal music library set up with a NAS.  I see many posts from 2 months ago.  What is the latest?  I need to purchase a NAS - what to get?  2 months ago people were using SonoPhone for Sonos and could not go back to the original app Sonos S1 Controller.  Catch me up please.  I welcome your advise and tips.

Thank you.
