Cd storage / backup

Music Vault from Neal @ Sound Science. 

I used a Mac computer to rip all my CD's to FLAC using xAct audio software.  I use a Google wireless network (3 piece) which employs a mesh network between its devices.  This is much better than traditional routers and extenders.
I copy all Flac files to NAS devices (wired) from my Mac.  From here I have another mac in my media room that runs Roon.  Roon does a great job of creating a library , getting content related to your media and presenting it.  

i have several systems running Roon compatible devices.  For critical listening I use an Auralic Aries and OPPO UDP-205 for lossless  and HI-RES playback.  For whole house and party mode I have several Sonos devices which also work with Roon.  The Roon software itself runs on any computer, tablet or smart phone.    

Bluesound vault II works very well.
