I dug out my old Quadaptor to solve a new situation. My large living room has a pair of Bose301 speakers that were spacially wonderful, but the rig needed a subwoofer and ambience. So I connected the Dynaco input to the front output channels of the amp, and then the front output to a Sony selfpowered subbwoofer and the two rear outputs to two Bose161 speakers. It solved both problems, making the solution a sweet listining environment.
