I hear that because coaxial digital cable is used to transmit the digital signal, the data is passed as 1s and 0s. Therefore the actual signal is either present or not present. It would mean that using a very cheap coaxial digital cable would produce the same results as using a very expensive £150 gold plated one. However, a lot of reviews claim some of these cables are much better than others. How can an expensive one better if the signal is digital? Is it worth buying one at all, or maybe I should indeed stick to using the default cheap coaxial digital cable that comes with most DVD players?
