I had an all VD system, consisting mostly of Genesis ICs and PCs with Rev speaker bi-wire cables. I found the VD cables to produce a lot of energy, but unable to resolve innermost details in a meaningful way. I kept getting the feeling something was missing, and I even discussed this with Ric, who I consider a friend.
After demoing a number of cables, including Stealth, I found what I was looking for in the SR cables. I went to an all Tesla SR system, including the Powercell 10-SE. I now have the resolution and imaging I was missing, with a more organic, musical and life-like presentation than I ever had before. I also don't have binding posts in danger of snapping off due to cable weight. You can see my system under Fplanner2000.
The SR cables have definitely taken my system up a few levels from where it was before. Yes, cables do make a difference, but the only way to tell is to try them in your system. I fortunately had a very good dealer that made my experimentation a lot easier than it might otherwise have been. Good luck.
