All of the things you are talking about are measurable. Different cable mediums will hae different properties, including transmit speeds. But the transmit speed differences would be so small that imaging would not be affected. There are other differences that could cause an audible difference.

Even if you were to assume that you could create sub-microsecond delay into a system with a 10' longer cable, the variance created once the signal is turned to sound waves and passes to your ears would be far greater.
