No, converting MP3 to CAF does not cause additional quality loss — CAF uses lossless compression. However, any artifacts already present in the original MP3 file will persist in the CAF output.
CAF files are typically 2-5x larger than equivalent MP3 files because CAF preserves all pixel data. This is expected and necessary for lossless quality.
