I’ve been using a Wireworld Aurora 7. 12 ga silver clad OFC. Its flat design makes it pretty flexible. I have it folded back with about an inch radius.
I have the Wireworld Elektra 7 which I believe is a higher model. It is quite flexible but the connection between the plug of the cord and component isn’t firm and always loose.
Performance wise, after comparing the Elektra 7 to Acrolink power cords, I figured out that the Wireworld is inferior in sound quality. It’s decent for DACs but does not sound good with amps.
