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