Question about double run cables

Hello,

I am wanting to order a single run of Goertz cable for my Magnepan MG12's.

I wanted to order a 7 foot pair of MI2's. But my dealer told me he is currently out of MI2. He told me he can give me a double run of MI1 for the same price. Note, this would not be a bi-wire cable, it could be two cables using the same connector, making a double run.

The MI2 is exactly twice as big as the MI1, so by doubling up the MI1 it would the the same gauge equivalent of a single run of MI2.

My question is, sonically would there be any difference?

Also, how good are the Goertz banana connectors? I have to use bananas on the magnepan end, but I am thinking about them for my amp end, for ease of hookup in a tight space.

Thanks
Nick
