Damn, $400/m ???
I guess it's for some too rich and very obsessive audiophiles.
Even studios who own high-end consoles don't spend that much on cabling...

I've seen regular Neutric plugs and Proel cables on Trident80 console, and
Monster cables connected to SSL9000, not even close to $400/m.

Don't get too obsessive with cabling, keep it real.

:D
