Here are my components: Onkyo TX-SR607 2 polk audio tsi300 floorstanding speakers infinity tss-500 (5.1 surround speaker system). What would be my best setup? I know the tx-sr607 has bi-amping capabilities, but I have read that that gives you minimal improvement in sound. Where should I place the polk audio speakers? In front? In back? As you can probably tell I am a complete noob and yet spent close to $1,500 on this system.
