Yeah, Sat; the receiver/preamp has to have circuitry to send out two voltages instead of one(but of reverse polarity)and the amplifier has to have circuitry to "re-reverse" them. Both units have to have the balanced circuitry provisions. Yes, assuming that the amplifier does have lower gain on its balanced input, an unbalanced signal(without the double voltage)fed into it would result in a lower sound level.
