NBS or Siltech

My system is tube based....I have Jm Lab Mezzo ,Wadia 860 and Cary 805C which cabels will match my system better? Can anyone help? I do only consider NBS and Siltech....
Siltech, but only the 100% silver models.
Have you bought your cables yet? I am comparing Siltech G3 with NBS Monitor 0. Can you contact me please. damokanyc@aol.com rgds, david
