Connectors with Screw Terminals

I don't need the DB connector but I need some of those "green" connectors for a Channel Plus audio system. Does anyone know where i can find come of those? They are similar to what comes with the Elk M1.
The "green" connectors are Phoenix-type pluggable screw terminals. I'm not sure of the pitch that the Elk uses.
