Cerious Technologies graphene/liquid ceramic cables

These are somewhat of a new technology, and have gotten absolutely superlative feedback across the web. One could say they are affordable.
They utilize a mix of copper/silver and carbon nanofibers, with a liquid ceramic acting as an insulator/damper. This latter property makes them behave such that they need substantial time to settle after having been moved.
Apparently a fantastic value. Please, describe them and compare.
