My first HT processor was a Golden Theater -- it's truly a shame that they folded as it was a great sounding unit for the money, and unlike many other processors, the back panel actually had room for those that have a penchant for audiophile cables
They were just about to release an upgrade to the GTX-1 which would have been a tube based gain stage.
Depending on what's failed, it should be repairable -- the question is... what failed?
