I think my equipment is good enough to be able to detect an audible difference, if there is one. I'd be surprised if anyone else can, as I've had three volunteers to try it also with the same result - one is an audio engineer. All I can think of is that others who say they can hear a difference, perhaps they had a defective cable in the first place and the D-Fi does sound better.
Conclusion: Not worth the upgrade, except for aesthetic reasons for a nicer cable.
