Power regenerator. Your power grid is never great, once you realize the difference you hear in that late night sound from the low usage on the power grid that supplies your house, and you can have that in the middle of the day.... you will never go back to just plug into the wall or just a conditioner.... try it...
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 .
