If you are concerned about it, you can always have Linn check it for you. The only thing is, Linn has informed me that Linn repairs must be handled through Linn dealers, which may be kind of tricky if you didn't buy from a Linn Dealer. Of course, you could offer to pay for the dealer's services in facilitating the return, but some dealers won't do that either. Don't think I'm anti-dealer here. In fact, my entire current system was purchased new. But I don't think I'd be very comfortable going into a dealer I hadn't done business with and asked them for help with a problem product.
