&gt; HDMI all digital correct? So isn't a cable just going to work or not work? \n\nNo.  Wrong. \n\nWith a quality cable, the ones come through straighter, and the zeros come through rounder.  With a crappy cable, the 1s and 0s acquire rough edges and look like they're typed on a fourth carbon paper from a 1932 Olivetti.  In fact, some of them get turned into lowercase ells and uppercase Qs.  Do you have any idea what a string of Qs sounds like through your speakers?
