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