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