Hi: I have received a few days ago Elrod Power System ESP 3 cord for my Hydra. For what its worth I was literally shocked how sound improved in my system. All David Elrod power cords, on my opnion, radically different from all other power cords I had or auditioned (King Cobra, fat Man, FIM Gold etc). Its sonic signature, for my ears, is of stripping layers and layers of veil between me and musicians creating "spooky" feeling of realism. I don't think words "immense transparency" come even close to my listening experience. In Hydra, ESP 3 created also sense of efforless bass, unrestricted dynamic range and more natural (timbrally accurate) sound. I absolutely did not expect from this small power conditioner along with EPS 3 such giant improvment and i am immensely happy with my choice!
