Receiver with sleep funtion

I want to fall asleep to sweet music, and wondering which surround receiver has sleep function ?
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.
