This shop is authorized to repair Denon audio equipment. I took a Denon unit there for repair. The owner said it should take a week or so to fix. I checked in on them 2 weeks later and they had not started yet. At 5 weeks I checked in again, they had attempted to repair with a replacement part which did not work. They said that they had done all they could, it was unfixable. I had it fixed elsewhere.
