Basically my question is whether the conversion from ALAC to FLAC or vice versa remains lossless in quality.
I ask because today I converted a few files using XLD and I accidentally left the output format as both FLAC and ALAC and the ALAC output file was actually a different size of the originally ALAC input file.
I'm in the process of converting my entire iTunes library which is in ALAC format to FLAC for use with my Hifiman. My CDs were originally ripped in iTunes using the ALAC option and error correction. It would save me a whole bunch of time if I can just use something like XLD to convert my library to FLAC.
I hope someone can clarify this process for me.
