The quality depends on the service and release, the “highest quality” can vary from 192 kHz 24-bit FLAC to 320 kbps MP3. Also, Qobuz releases seem to be mostly FLAC, sometimes 24-bit and above 44 kHz sampling rate. Qobuz lists the quality on the release page too, so you may want to check that out before dling.
