<font color='#000000'>All audio signals travel along a cable at a large fraction of the speed of light (0.7c); the frequency-based deviations from that typical velocity (propagation time), while real, are miniscule by comparison. When considered in light of the typical length (2 meters or less) of an audio interconnect the technical term for the difference in arrival time to your ears is "not freakin' much!" We're talkin' picoseconds here, about as far below the threshold of hearing as individual atoms are below the threshold of sight.
Of course, this is besides the question of whether said cable can actually correct for the propagation time variation!
This is a great illustration of how a kernel of scientific truth can be distorted for marketing BS to ensnare the innocent!
But...if they can indeed synch your VCR clock or enable time travel, then they're worth it!</font>
