I have a Sansui AUX711 integrated that works divine with a Denon CD player on Paradigm front LR speakers. I recently bought a new Yamaha AV receiver - RX557 to pair with a couple of rear Infinity speakers, AR sub & a new center. I am a little confused on trying to get the best of both worlds. I want to have stereo with the Sansui & HT with the Yamaha using the same front LR speakers for both. Can I use the main preouts of the Yamaha running into the Sansui and then connect the rear speakers, center & the sub to the Yamaha? Will the home theatre connected to the Yamaha work in this setup? What configuration do I need for the Sansui when I am playing the HT wih Yamaha? That is, apart from using a speaker selector like Russound ... Appreciate answers as I am going crazy being a newbie!
