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