Does Cone Pulley Configuration change Mechanical advantage?

[MWF FEED]

Ill probably get shot for asking but I am at a loss as to the answer to this.

Does the cone pulley configuration change the mechanical advantage??

Everything in my simple mind tells me that configuration E-D even though the slowest spindle speed does give the most mechanical advantage?? Or is there no difference regardless of the belt configuration?
