Thank you for the clarification.
I did look up the definition of "regenerator" and this is what I got:
re·gen·er·a·tor ri-ˈje-nə-ˌrā-tər
1: one that regenerates
So you were spot on! lol (did you cheat?)
The stable AC voltage is what you can get on the cheap - as you propose! The rest is debatable as all things but I feel these products are blurring the lines between bluster and value. In other words, these regenerator products have hefty margins.
My voltage rarely moves. Have seen it at 119 & 122 but generally constant 120. When they built our home in a large horseshoe fashion here in PA, PECO added a new plant just for the 150 homes that were constructed in 2012. Last year, all the homes across the street from our development went dark for 48 hours during a storm. Nobody on this side of the street was harmed.
I remember similar situations that I had when I had DSL back in the 1990's. Your speeds depended on how far away you were from the Central Station. Electric, data, it's all about the infrastructure that surrounds you and it just seems PS Audio is not really looking to inform buyers about that fact.
Thanks for sharing your knowledge, Erik. While I designed and built my basement listening room/bar I neglected to put in dedicated lines because I just did not know any better then. I don't know that I will fix anything by doing it, but do believe that 20 AMP lines make a difference as I had my nephew do it for his basement and his entry-level electronics sound clear and concise, even at volumes where they should not.
