i have an existing audio-video surround component set up with an AV surround receiver acting as the preamp during stereo music listening. in 2 months from now, ill be having a dedicated stereo preamplifier. how do i hook in this one into my existing set up if ill be making use only of it for music and the receiver only for movies? would i be needing a T or Y RCA connector in the inputs of my stereo power amps to accomodate both the reciever and the preamp outputs going to it? is would there be a wiser solution?
