I have the Heil Pro Set Plus headphone. This set has both the HC-5 and HC-4 elements. I was thinking if I really need the HC-4 "DX Machine" element due to menu 8-9 in the Mark V. Adjusting the setting to give more higher frequency response in 8-9, does this not accomplish the same thing as the HC-4? Thank You in advance. john-n3drk
