I haven't heard any Gabriel's yet, however, from reading the threads it would seem they are more comparable to the Jade and Stealth cables than to the Virtual Dynamics. I've owned Stealth, Jade and Virtual Dynamics, amongst many others. The Virtual Dynamics will sound more powerful and dynamic than the Stealth or Jade, but they are also have a more forward presentation that I did not care for. The VD cables also had less of a three dimensional stage, and didn't present the natural sounding instrumental colors and hues that I get from Jade, Stealth, and PAD cables.
This of course is all just my opinion. I do know many VD fans who love that forward, dynamic and powerful sound. They love the excitement of that front row presentation. So it's all depending on your musical tastes. I would say that Virtual Dynamics is in an entirely different camp than Jade, Stealth PAD and from what I've read, the Gabriel's as well. Which camp you wish to be in is your call.
