The firmware in a 2K servo verifies the position of the servo arm two thousand times each second, 
while the firmware found in previous servos verify the arm´s position one thousand times per second.
This greater number of verifications makes for a very precise servo, and gives it a more "solid" feel.

It is recommended to use a booster cable with 2K servos to ensure steady voltage at all times.
