Many different decks have different preamp voltage. It seems the higher end decks have a higher voltage. I want to know the advantages of this. My deck has 3 pairs of 5 volt preamps outputs, Is this good?
the main reason why higher voltages are better is because they induct less ground noise into the system. with the gains set near max, you'll bound to have some noise. maybe thats why high-level inputs have more noise?
