Receiver with sleep funtion

I'm sorry, but this question crosses the line for me.

Have you done any homework on the subject or do you expect us to do this for you?

I have a preamp with that function but it's a bit dated so I won't even mention the model.

I don't want others to do my work - just spare a minute and let me know if your surround receiver has a sleep function.

Let me rephrase the question then - does anyone know if upscale Denon units have sleep function?

I tried to find this on info on line, and couldn't find it.

Get a timer, probably be much cheaper.
