I have a PS audio pp5 I purchased used which replaced a relatively cheap panamax. At first I actually liked the panamax better, the pp5 made the sound very bright even through it may have possibly had more detail to it I could not get past the brightness. After putting on a DIY power cord and replacing the fuse the sound was much better. And then after buying a counterfeit PS audio AC 12 cord on ebay that PS audio was nice enough to replace it with a genuine one at no cost! (who does that?) and installing a SR orange fuse it now sounds awesome. The pp5 has a multi wave feature which seems to make the sound more fuller and not as thin, it comes with a remote were you can turn it on and off from your listening position which makes it easier to hear the difference.
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 .
