In the Thread: It’s mad, mad, mad... electricity.
Post Subject: Wouldn't It Be Nice?Posted by Paul S on: 9/22/2021
Amir, this is the most popular thread at GSC for a reason. While most people don't give bad electricity a thought, there are obviously plenty of audio people who are looking for answers to these questions. Since my AC provider went "Smart", the AC where I'm living now initially got worse for the change, and by now it has settled down to being more consistent, not as good as it used to be at its best, and not as bad as it used to be at its worst. I never would send money to Pure Power, because of the odds of getting either nothing at all or of getting chronic problems in return for the money. However, I did pay some attention to what people had to say about their PP experiences, over the course of this very long thread. What I got from the aggregate of many user anecdotes here is that Pure Power never did "correct" the power grid AC, and it always injected its own sound. And some PP users have said that the best un-treated AC still sounds "better" than typical Pure Power sound. I have long suspected that the PP's PWM output has an effect on typical component power supplies that alters the sound in a way that happy PP users like. GSC member (and my friend) Mark has consistently the best AC I have ever heard. I mean it as the highest compliment when I say it is not a problem anymore. He has dedicated, in-phase hi-fi circuits with unbroken, separate, dedicated neutrals and grounds, and he has good quality AC outlets. But no PP. Over the years he added a solar powered UPS system that includes 2 giant Tesla batteries, and he has control (on his phone!) over how the system is configured. To my ears, his system still sounds best powered by the optimal grid, compared to the batteries alone. While I am curious as to whether a PP 3000+ would further improve things, I would not be chasing this if I were in his shoes. For another thing, he uses two 1,200 Watt monoblock tube amps, and not sure how that would play with PP.
