I have owned a pair of KLH Nines since 1992. There is absolutely NO benefit to replacing the stock power cords - contrary to what the neurotically obsessed will claim! The power supplies are low-current and adequately designed! Their sound starts there! Not from the power cord to the wall AC outlet!
KLH model 9 electrostatic Speakers
I just bought the above speakers, I like them a a lot , I am thinking if it’s possible to replace the power cord on the power supplies. On this speakers? Thanks B
