Kimber 4tc good enough?

I'm currently using a single run of kimber 4tc to drive my persona 7f speakers with a hegel h360. While the dealer I bought the speakers from suggest wires don't matter I notice the stuff he uses is bigger than a garden hose and a product the shop doesn't even carry. Would bi wiring with a second pair of 4tc wires instead of the jumpers matter? 
Can the 4tc choke the speakers of watts?
