What you described is not a re-tip, your cartridge will be refurbished with completely different stylus/cantilever combo.
Re-tip is just the stylus tip replacement on original cantilever, but the original method is press-fit (the one and only benefit of aluminum cantilever), it will be more complicated for re-tipper to glue just the diamond, so they will glue the whole new cantilever to the collar. The cantilever/stylus combo mounted together by the companies like Namiki or Ogura in Japan.
Of course you can buy a better cartridge than refurbished DL103 for your audiomods tonearm.
