I have an Adcom Power Amplifier which I bought to run additional speakers off my Pioneer VSX-D705S reciever ( 150 Watts by 4 ). On the Pioneer I do not have a line out to hook up the power amplifier. My question is what do I have to do to use the power amplifier? I have checked different recievers and very few seem to have a line out for additional amplification. Everything also seems to be home stereo when all I am after is music. ]
