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