He’s correct. There is no loss and the extracted data from FLAC, ALAC or WAV is the same.
There was a period of time when at least Stereophile was promoting the idea that the decompression process itself could result in audible effects like jitter depending on the device, CPU, algorithm, etc. and that because FLAC and ALAC used different decompression methods the three (FLAC, ALAC, WAV) could actually sound different even though they held the same data. Honestly I’ve never lent that theory much credibility. It certainly is possible that poorly implemented software with highly variable CPU performance could make for poor replay experience but I’ve never actually heard that happen.
If it did happen it would be very much replay device dependent, and in the 21st century I just can’t believe devices could overlook these issues and not mitigate them. Decompression, buffering and clock driven DAC is just not rocket science anymore.
