An Audio Research D350 came into my local shop recently to be sent out for repair. The owner had called ARC to arrange for them to repair it but they said that it was never a very good amp to begin with and recommended that he just buy something new. The owner was quite angered by the hassle he encountered and was not impressed that they said it was never a very good amp to begin with.
The amp was sent somewhere else and was repaired.
