Flexible Power Cords

I'm not sure what you consider budget end price wise, but there are two cables with which I've had good experience.  Cardas, clear reflection in my case, high quality, neutral and very flexible.  Cardas are moderately expensive.  Also, Kimber Base PK10.  Good solid performing, flexible power cable at a much less expensive price point.

2 meter lengths is the minimum recommended length for power cords. Good quality power cords act like conditioners and two meters provides more than shorter lengths. I had the opportunity to compare a couple of the same brands on my system and there was a notable improvement in two meters over one.

What is your budget range per cable?

Take a look at the DH Labs Power Plus Cryo - exceptional performance and very flexible at a price that won't break the bank.

     I've been using Zu's Mothers for a couple decades, on all of my sources, with excellent results and can't imagine a rationale for replacement.

                                  VERY flexible!
