I run a Goal Zero Yeti 1000 for my pair of Devialet D440 and it's a game changer, bests every other conditioner by a mile and a bargain for the level of improvement. I do use SR Galileo PC's to the amps. Magical and without comparison. According to the reviews sounds identical to the Stromtank.
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 .
