The three best power cords I've had beyond the VD are the Stealth Dream, Dream State and Silent Source. I've also had the old Synergistic power cord, but haven't heard the new Tesla series.
I agree with John 100% about the difference between the VD and the more natural Stealth Dreams.
The Silent Source Power Cord ( $900.00 ) is not well known, but a real sleeper that you might try. This is the blackest, most revealing and most true sounding tonally power cord I've ever heard.
In my system, I went with the Dream State Spritual Dream series ( Lucid, Veridical and DreamCatcher ). They're warmer than the Stealth Dreams and work extremely well for me. IF you have Dream State power cords on EVERY component, the soundstage is a hologram.
