WHICH TYPE OF BOOST CONTROLLER IS BETTER, SOLENOID OR STEPPER MOTOR?
While stepper motors are quieter, they are also slower to respond. Solenoid boost controllers are much faster responding but are louder. While solenoids can be mounted in a way so that they are virtually silent, you cannot get a stepper motor to respond faster than a solenoid type. We recommend solenoid type boost controllers like the Apex AVC-R.
