@craig - I agree with you in that you would think regenerated "perfect" AC would be the better choice, yet so many audiophiles seem to go with the passive conditioners and I'm not sure why. I myself have an Audience conditioner, which I like very much, but I've never tried a Power Plant. I don't think cost is the issue as the better conditioners are at least as expensive as the power plants.
Power regenerator vs conditioner
If the goal is to improve the sound quality (soundstage, detail, dynamics, etc) and the issue is "noisy" AC, it would seem to me that a power regenerator such as PS Audio P15 would be far superior to a "conditioner" such as a Shunyata Denali or Hydra or Triton. Is this correct? Thanks .
