I'm trying to figure out what the actual damping factor of my system will be. I need to know the source impedance of the amplifier, resistance of the speaker cable and impedance of the speaker to do this. Specs for the DCi 8|600DA mention a damping factor of 1000. Does this mean the actual output impedance of the amp is 0.008 ohms? (DF = Zload/Zsource or 1000 = 8/.008) Thanks!
