All the talk about pre/pro has got me wondering. In the car audio world a head unit (pre-amp) that is putting out 4v-8v is quite good. Those with 1v or less aren't considered worthy. In the home audio world is the higher the pre-amp output voltage the better? I remember reading about someone on the internet who was running 32v to his amps. I couldn't believe how high that was. It seems excessively high. And I know he was doing it with a unit that ups the voltage coming out of the pre-amp. I think they call it a line driver or something? I checked to see what my Outlaw 1050 put out but it doesn't say. I would just like to learn more about this.
