No, converting M4A to CDDA does not cause additional quality loss — CDDA uses lossless compression. However, any artifacts already present in the original M4A file will persist in the CDDA output.
CDDA files are typically 2-5x larger than equivalent M4A files because CDDA preserves all pixel data. This is expected and necessary for lossless quality.
