I would say that something is definitly wrong. First I would pop the cover and determine if anything has come in contact with the transport. If you determine that it is free from any foriegn objects in there. Then I would contact McIntosh and get a RMA# and send it back to them.
I can't speak as to how they will handle it, but I had an experience years ago with an MSD4 and it cost me shipping costs to get it them. They fixed it for free and shipped it back in a new box. They may not be as generous with you depending on the issue, but they will fix it.
