All receivers I've ever owned (probably about 5 or 6 total), have made one or two switch or relay type noises when you power them off, but this sounds different. I just got a Denon 4311CI yesterday and I've turned it on and off a number of times already, but just noticed this noise when powering off. Not sure if it just started, or it has done it every time.
Here is a link to the video with sound of powering off. Click on the pic to see the vid.
Thanks!!
