I had the 4700 for a few weeks. It was a very nice receiver and had a good display but it was awkward to use. A lot of the controls are hidden in the function buttons and it's not easy to change the disc play mode on the fly.
The other problem I had with it was the way random track worked. If you skip in the middle of a song, it goes to the next track and not the next random track. I've never seen anything with a random track function do that.
Ultimately I returned it and got an Alpine deck which I love.
