When something is labelled 1 to 79, I realize that there isn't any physical meaning behind the numbers because they are dimensionless. But when I look at my Denon and it gives me the number in units of dB, I have to wonder what the engineers were thinking. There must be a reason behind labelling the numbers in dB. I still think it's related to the voltage across an 8 Ohm resistive load with a signal of known frequency and amplitude. Now what that translates to in the real world is a mystery to me.
