Whilst the cable will affect a number of variables, a good 75ohm cable will transmit the signal with little to no errors, as the data is digital it cannot be altered by a cable without introducing errors. The signal is also transmitted in the MHz domain well outside the audible range.

I read a definitive test recently concerning HDMI cables where the test involved a section of video where each frame had an md5 hash generated so that the captured frames could be compared with the original to determine whether or not expensive cable made grass any more vibrant or flesh tones more natural, the result bar one or two frames that had single pixel errors showed that a £1 cable was as good a transmitter of data as a £100 cable.
