I recently pruchased a new set of main speakers and it has been suggested that bi-wiring the speakers will make them sound even better. I contacted Onkyo and they strongly discouraged me from doing this. I guess I have a two part question: Does bi-wiring really make that much of a diference and has anyone had any experience bi-wiring an Onkyo receiver? The reciver is a TX-DS595. Thanks for any imput.
