Congrats! If the 4700 is brand new but from their older stock, you may even ended up with the AKM DAC on board! If not, so fyi, the TI DAC (PCM5102A) is very comparable to the 5200's PCM1690, you can download the data sheets to see the extremely small difference in SINAD yourself.
I always find the "Denon sound", even "Marantz sound" bland and would expect the 5200 would be the same too. If you look at their specs and measurements (where available), you can understand why, all those AVRs in the mid price range should be transparent, that is, amplify the signal linearly without adding their own "sound signature". So if you hear the same quality now, good for you, if not, just get used to it and your ears/brains will eventually agree it sounds the same as the 5200.
That's for music, for movies I would say it is quite likely they will sound a little different but it should be hard to compare without having both hooked up and can be AB compared momentarily. That is near impossible to do for most people but without doing that, anything you perceived is anecdotal to others.
