Steve, it seems unlikely that the parts delay would be extended, but if they can't repair within a reasonable time, Federal warranty law would require an equivalent replacement.
If this would end up with a factory refurbished replacement unit being supplied, it would start a new warranty period running(typically 1 year)and wouldn't be limited to the original 3 year warranty period.
I've never thought that Integra products justified their premium price and my experience with Onkyo factory refurbished units has been trouble-free.
