I have not heard the Sonoran or Sahuaro but replaced all my Transparent Reference and Ultra XL cabling with Ensemble a couple of years ago. The speaker cables sounded better than Transparent on my two systems, for a lot less money, so I sold the Transparent and stopped shopping around and comparing cables. If you can find the Ensemble used, you can try them and then just resell them if you don't like them. Used, I paid $600 for an 8-ft pair.
