In my experience I found that shotgun cables offer only very mild difference if any to the non shotgun.
Shotgun connection
I have following case regarding loudspeakers connection.
I have a speaker cables that have two internal wires.
I would like to connect each loudspeaker using double run of my speaker cables, so I have four wires on disposal.
In that case I can connect the speakers in two ways:
1. Each of the two wires on the cable goes to the positive and negative speaker terminals.
2. Both wires within the each cable shortened with each other and one cable goes to positive, and the other to the negative speaker terminal.
The first variant is the gain that wires the plus and minus are twisted together.
In a second variant the gain is that the dual cores plus and minus are better insulated from each other, because there is external insulation.
How is theoretically better?
