I just answered your post in the SE200 thread...Thanks so much for that! I understand the SE180's file management well now. A separate thing I'm wondering is...
Do all of your offline downloads have to be re-downloaded when you have to manually update the sideloaded version of both Tidal or Qobuz? That would be pretty rough if I have a large offline library.
Also, I know you have demoed your fair share of DAPs and that it also depends on amps and circuitry, but do you have any general description on the difference between AK4497 and 4499 dac chips?
They do not need to be downloaded again when you update as long as you keep the previous version of the app installed, then install the new one. The new one will overwrite the previous app, keep all app settings and downloads. If you uninstall the old app before installing the new one, it will wipe all settings and previously downloaded music.
