I would agree that the power regenerator you mentioned is better than the power conditioner. I am currently using PS Audio P12.That's what I have. The difference in the sound of my system before and after is not subtle. Every bit of line noise I had before the P12 is gone. An investment worth every penny.
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 .
