Like sr20 said no the preamp voltage determines the quality of the sound through the rca's.

The quality of the parts used in the preamp section of the headunit determine the quality of the signal leaving the rcas, the output voltage has nothing to do with it. A higher preout voltage simply lets you hit full output on your amp with a lower gain setting, making any emf interference induced in the rcas on their trek from the headunit to the amps less significant. Anything over 2V should be plenty to eliminate noise in all but the worst installs though.
