i have a pioneer vsx-512s receiver, pioneer sg-505 graphic eq, kenwood jl-975av towers along with some energy A3+2 towers. the energy towers allow single speaker or two speaker output per tower. what i was wanting to do is get most out of receiver using rear speaker outputs in a bi-wire or bi-amp configuration. not quite sure how to go about that or if it is possible? could you help with this or is it a good idea? thx
