Shunyata hydra and power cords really dropped my noise floor. I didn't really wanna think it would but once demo in my house it was an eye opener. I'm in a loft building with 15 amp service running tube and ss gear . I think conditioners are not gonna make a mediocre system great but they will make a great system just a touch more accurate. Prior to the shunyata I had just a monster power strip plugged into a Panamax. That combo did not seem to do nearly as much on my setup .
