Damaged Receiver, No Sound Output

The box appeared intact, but the internal packing foam was broken into pieces and the receiver arrived dented. Once speakers were connected, no test tone or sound came from any channel. The unit had to be returned and was unusable. This is disappointing given prior positive experiences with other Denon speakers and receivers.

Cons
  • − Damaged internal packing foam
  • − Receiver arrived dented
  • − No test tone or sound from any channel
  • − Had to be returned
  • − Unusable
