Power cord replacement suggestions

Does anyone have any experience with the mad scientist power cord, good or bad? I dont have the time or financial resources to try umpteen different brands, so would love to hear from people with experience.

In my experience, power cord change at the source makes the biggest difference.  I started out with my dac and the difference was huge.  Then I changed the power cord on the amp, and there were noticeable differences, but not as big as the dac.

Well, everyone can't be wrong. Far be it for me to reinvent the wheel. We'll start with source, after i find a powercord.

Here are three options of power cords that are very worthwhile to look into at three different price ranges, all inexpensive in my opinion. I own all of them and I can attest to the fact that are all very good and will compete with power cords costing between $1000 to $2000 or more.
Send me a message if I can further answer any questions for you regarding these power cords.

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.
