Audioquest Sky/Evrest or Purist Dominus/Anniversar

I have for the moment cables for my systems: Audioquest Sky interconnect Balance and Evrest Speakers cables and Power cables Elrod Satement.

I have envie to update to the Purist Audio: Dominus ferox or 20th Anniversary Interconnects/Speakers & Power Cord ?. Any comment or recommendation for this crazy and expensive decision ?.

Thank you.
