Synergistic Designers Reference

Hi Folks:

Several years ago at the last NY audio show, I heard a demo of these cables with active shielding. With or without the shielding installed, the cables sounded phenomenal. One of the best I have ever heard. The others on my short list of speaker cable would be Kimber Select and Monocle, Kubala Sosna Emotion, Cardas Neutral Reference and my current cable the H.T. Pro 11+.

Can anyone compare or contrast the above?

Is the Synergistic only at it's best when you are also using the same series of interconnects?

What is the successor to that series and does the Designers Reference cable offer good pre-owned value as far as reference quality is concerned?

Thanks for your help.
