Virtual Dynamic Master or Kubala "Emotion" PC

Has anyone had the chance to compare these two Power Cords, and if so what was your thoughts. This may not be fair as the Virtual Dynamic Master Power Cord cost 2x as much, as the Kubala-Sosna "Emotion" line.

Thank you
The VD master will bring your system to life. Voicing changed,detail became greater, dead quite, black, black backrounds.You now can feel the emotion of the music and what the artist is trying to convey. Your heart will race because the emotion that you feel with this cord. This is the greatest upgrade I have ever done. As for the Kubala, I cannot comment on, There isn't a dealer in my area. Hope this helps alittle. Brian
