The sample size doesn't appear to be hurt. Stays as 24-bit.
Only the sample rate gets changed from whatever it was (96 or 192kHz, for example) down to 48kHz.
So I'm currently keeping everything as FLAC with Amadeus and converting to Apple Lossless elsewhere, later, (with XLD) in order to have hi res ALAC files.
Saving/exporting hi res to Apple Lossless downsamples to 48k
