The “GENESIS” is the original RCA plug with our new collet chuck clamping device. This newly improved collet chuck structure which is placed on the lower middle of the sleeve actualizes secure holding to the connection part due to its independence from the outer sleeve. In In addition, because of the coating of high-viscosity grease on the screw part, you have never felt like this smooth rotation before. It is not only for your feeling pleasure but also for the vibration damping between the inner body and the outer sleeve.
