The BEST kept secret is this: there IS no "best" cable for every system. The "best" cable for a given system depends totally on which amplifier is driving which speaker. You can put together a system in which Valhalla sounds like junk and old MH-750 Shotgun makes you weep with joy. The same is true in reverse.
Now if you mention your amp & speakers, then we might get somewhere :)
