Thanks for the replies guys. The reason I'm worried is because the CD player is a 12 year old Sony 5 disk changer and skips on occasion during a really bass heavy peak (and these were through my old Bose 301's) or when one of my roommates would stomp (jump) his feet on the floor. The reciever is gonna be shelf mounted so that shouldn't be a problem. I'm also intrigued by this Tennis ball solution. I just want to play it as safe as I can with spending the least amount of money possible.
