I can't believe there is so much misinformation on this thread.
1) Backups go bad. Are you backing up to paper tape? Tape? Backups don't fail, its people who fail to backup. If you are backing up to disk, all disks will eventually go bad, but the chances of both your source disk and your backup disk going bad at the same time is very rare. You do have to be smart about your backups: if you are getting disk errors, fix them or replace the disk, make sure your backups are operating every hour/day/week.
2) Errors reading music from HD. This is the most simplest thing to do on a computer. It's so easy, its built in all Macs, you insert a cd, iTunes reads and imports the disc, and you doubt;e click the album icon, and it plays. A 4 year old can do this. iTunes sucks for audio quality though! If you use any of the music apps that run on a computer: Roon, pure music, or a dozen others, you break up the parts of ripping music from the playing music apps.
3) Its been proven over a dozen years ago that reading music from a HD sounds better than from a CD player. I got rid of all my cd/sacd players almost 15 years ago.
4) If people play cds or albums because they can read the liner notes, you are missing out on much more important information that Roon provides.
5) networks are a problem! There hasn't been a better time to install a robust/secure network than now. Network installation is very very easy. If you don't know networks, buy a mesh network and plug them in. If you can't do this, get the 4 year old I talked about above to help you.
6) so much trouble putting servers in different rooms. It's called being smart. You don't want any type of server in your audio room.
