No, absolutely not. The best power cords are absolutely inflexible. Some can only be bent on hydraulic press- they're THAT GOOD!All of our cables are candidates for Viagra ;-)
Seriously. In case you haven't noticed the most flexible are the freebie rubber power cords that come with everything. They are also the worst sounding. Therefore the more inflexible the better the sound. It's the Third Law of Audio. The First Law of Audio is the coolest looking speaker sounds the best. You are probably thinking now he's gonna tell me the Second Law of Audio and fat chance, you're just gonna have to figure some of this out for yourself.
Fourth law: If your gear doesn't require upgrades every 6 months, it doesn't qualify as high-end.
