First, I fully appreciate naming these little devices after some of the most powerful crafts in the world.
My question is, in terms of the Protector and SR-71B, how does balancing an unbalanced source be of any benefit, as within the source device, there is already a common ground?
 
Thank you.

Your question had been discussed in details in the Protector thread.  Do a search there.
