Dakmart (authorized) says you have the Denon 90 day warranty on refurbs, after 90 days Dakmart does repairs up to one year. You give up 1 year of warranty.

did the repair work on my Integra. They do warranty and non warranty work on all brands.

I agree with statement that it fails in 90 days or its good forever.

DVD players are a different matter. Moving parts like chucks go bad with wear. The longer the warranty the better.
