After struggling to choose a reasonable amplifier for HD800, I narrowed down the options to three candidates: 1) RWA Corvina / 2) RWA Cassabria / 3) AnalogDesign Svetlana 2. Since Svetlana is hard to get in US, I am inclined to have RWA's  products, specially Corvina unless Cassabria has a remarkable improvement against Corvina.
 
Assuming I will have either Corivna or Cassabia, I would like to know what balanced cables people does usually recommend. Based on many advices and my own research about the cables, it seems the followings are pretty strong candidates.
 
Toxic Cable
Moon-Audio Black Dragon v2
Charleston
Double Helix Molecule
 
I also heard it is not a good idea to have silver cables for HD800. It would really help me if someone indicates me the full name of cables with where I can purchase it (ex. URL). My budget is maximum $350 for the cable, but prefer to getting a cheaper one unless sound qualities are not that much different.

Google is your best friend for searches. 

None of those you listed are hard to find.

I tried but it was hard for me to find some comparisons between these cables. Just want to hear that if someone has an experience of using these cables on HD800.
