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