For the ones I have heard: Gabriel Gold Rapture R or Stealth Hybrid. You would require 2 sets of each for biwire. You might consider Antipodes Kamako....a little faster and ok for Classe....I find classe a little thin, dark and slow. I am using MG Audio Planus III and am really impressed but they aren't suited for biwiring.....you could call Greg there just to check, they are great to work with.
That said, you might want to see what Steve at Gabriel has in stock.....I have a nine foot pair of Rapture R you might talk me out of.
