... mcintosh says best to go to a service center ...They don’t like to be in the servicing business that’s why they have a net work.
Nonsense. I’ve done business with McIntosh and the company delivers excellent service. Mac’s service network can save shipping costs and offers customers options. But to say the company doesn’t "like to be in the servicing business" is pure BS. In audio, McIntosh is the gold standard in service.
