I don't know what power amplifier(s) you may be using, but Outlaw amps will give you basically 100 watts into 8 ohms with a 1-volt input. The Outlaw amps that have a 200-watt output into 8 ohm rating give their full output at less than 2 volts input. I believe the 6 volts or so available on the output of the 950 is for headroom to make sure that an amplifier does not receive a clipped input signal.

I know that in some cases people try to provide a signal to a device that has a balanced input with an industry standard reference level of +4dB from a device with an unbalanced output at a consumer standard level of -10dB. In order to do so there is going to have to be some gain somewhere. Usually the output of the consumer device is not going to be able to be set to a +4dB reference and have the headroom it was designed to have.
