Driving the inter-connect cable---what a concept!Maybe another reason why the sound of any given cable is so system-dependent---it's interacting with the volume control in the pre-amp of every system it's put in.
This is either tongue in cheek, or your so wrong.
Just in case it was not tongue in cheek. The volume pot in a preamp has nothing to do with the interconnect cable, as there is and active buffer between them, totally isolating the pot from the interconnects
