Virtual Dynamics -- what has it beaten?

There's a lot of rave reviews of VD cables in this forum and elsewhere, but it's hard to put it in perspective unless you compare them to other cables. Does anybody have a side by side test of VD cables vs. Acoustic Zen, Stealth, Nordost, Ensemble, etc.? I tried the Audition interconnect, power and speaker cables myself and just didn't care for them, so I'm curious how they stack up against the competition.
