I agree that the speed of electricity is too great to influence the flow between a long and short cable. However, I stand by my statement that a noticeable difference will occur between a 4 foot cable and a 50 foot cable if the cable is 22ga. the smaller the wire, the greater the loss. A few db loss on a long run with a tiny cable is most definitely audible. Use 12ga cable or larger and there will be no problems at 40 or 50 feet.
