I have a quetion. I have been to the Yamaha site and can't find a Rx-550. Is it an older model that is no longer on the site? I recently was at futureshop and saw it there and took a look but can't find anything about anywhere else. Im pretty sure when i checked on the receiver it said 550. Anyways if there is such thing is the 530 newer or old that the 550, that is if it exists. Thankyou! YAY i get my receiver tommorow! so i guess i will have to check for responses in computer class!
