I do not doubt that regenerators do a nice job cleaning up the power or like you say in dirty power areas such as yours and NYC. I can tell you the Hydra does not choke the amp. I am surprised to what it does to be honest. Trust me when I say this, I was very skeptical of any power conditioners, regenerators, etc... for a long time till I tried my buddies Hydra 4 with a Copperhead PC. I was quite shocked at the results. Do me a favor and try or borrow one if possible and let me know what you think? I don't think they would be selling as well as they do if they did not work IMO.
