The only true advantage is the preouts on the yamaha, and it is the exact same price as the 600. Common sense would tell me to get the 5560 instead, or am I mistaken? I have no way of auditioning either since I am stationed overseas. Which of these receivers has a warmer, clearer sound. I don't like anything that sounds very bright or "metallic"?
