As stated in an earlier post, I need to run an equalizer for my vintage front left and right speakers. Could I take the preamp outputs for the front left and right of a Pioneer 1014, route them to the equalizer, and then to a separate stereo amp, for instance the Onkyo M-282 ? If configured this way would it affect any of the Dolby surround Sound or other digital effects, and why ?? thanks for any input, and for helping my search.
