The reason a longer cable might sound better is due to the gradual flexing of the cable. If the digital cable is short, at the point the cable is bent the impeadence will change at that point due to the dielectric being compressed and the center conductor moving closer to the sheild. This impeadeance change from 75 ohm to a different value causes an impeadeance mismatch which in turn creates internal standing wave reflection for the digital signal to try to get through. This intern causes "jitter" which creates digital errors that the d to a converter must try to correct.
When digital data is lost or its 0/1 transition state can not be accurately determined the sound quality suffers. The sound will take on a course or hard texture and will not be as airy or deminsional as it would be if the digital signal is passed in its entirty and at the proper timing.
So yes, it could make a difference in using a longer cable!
