This was my main receiver for many years. Everything works without issues.It is great condition. The photos show dust. The photos do not do it justice. Firmware will not update. If you attempt to update the firmware, the receiver will get stuck in a loop of updating and rebooting and never completing. You can simply abort this cycle by pressing the reset to factory default buttons. There is a refurbished sticker on the receiver because in 2015 I sent it to Denon for them to install a firmware update, which apparently required them to open the case.
