So the second amp at 2ohms nominal failed also? Weird if so. I have no experience with anything above a 7k2d so I can't speak for the 9kd, 11kd, 14kd but everything below especially the 4k2d and 2k5d (different design) have never had a failure. And we still use ours for daily music. Good luck and hope they get it figured out.
