droleg, I do have experience with Mad Scientist power cords. They're excellent and can be auditioned with a money back return policy. I also can heartily recommend Core Power Technology cords. Cords from both manufacturers are in my system.
Power cord replacement suggestions
If i were to delve into the fanatic behavior of replacing power cords, is there some concensus on where the most impact would be gained, whether on source, pre, or amp, or is it just different for every system and need to experiment. Thanks for any advice.
