try some 8TC, if it doesn't sound better, should be easy to sell for what you paid...maybe the dealer was afraid if you were told you needed more expensive wire, you might not buy the speakers...clearly the dealer likes the bigger stuff...
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?
