to Pioneer Elite's warrant concerning Authorized dealers.
First they say that on-line dealers are not authorized to sell the Elite brand, then they give a list of those businesses that are authorized dealers. One of these is Amazon.com which is an authorized dealer.
It would be my assumption that as long as the Pioneer Elite is purchased from one of these authorized dealers that the warranty would be effective. I could be wrong. I bought an SC-65 recently through Amazon. It probably would be worth an e-mail or call to Pioneer to know for sure.
