Ripping audio CDs would be equivalent to FLAC quality. Make sure to rip them to FLAC or any other lossless format of course.

There are a bunch of stores that sell FLAC that I use:

* https://bandcamp.com

* https://us.7digital.com

* https://store.tidal.com

* https://www.junodownload.com

* https://www.prestomusic.com

* https://www.prostudiomasters.com

Can't comment on prices, I didn't really do a comprehensive analysis.
