Not sure about the sleep mode Mark. I can’t find it in the manual, nor have I stumbled over it. Not only can you rename the inputs, you actually get to see what you rename them to on the display. You can also delete inputs so you don’t have to see them or cycle through them. Pretty cool feature.

Hansang,

I didn’t need, or really want to buy this receiver or do it to replace the Marantz. I would have preferred to wait a few months and see what Sherwood Newcastle comes out with, or Rotel. Unfortunately, I’m on my second SR/8001 that replaced a defunct unit. The second one also has issues that required me to send it in for evaluation. I decided to just buy something different and I’ll peddle whatever Marantz sends back to me. I do prefer this Denon over the Marantz though. So maybe this will work out….

Michael,
The 4806 is one heck of a reciever. I wish I would have just bought one of those in the first place. I wouldn't suggest you ditch it until something really cool hits the streets.
