I don't own the Puritan.But HolmAudio is HIGHLY recommended! I had a great experience there.
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 .
