No, converting AAC to S3M does not cause additional quality loss — S3M uses lossless compression. However, any artifacts already present in the original AAC file will persist in the S3M output.
S3M files are typically 2-5x larger than equivalent AAC files because S3M preserves all pixel data. This is expected and necessary for lossless quality.
