are they making room for '14 models?
Only on the spec sheet. You won’t hear any difference between these and the DACs in your x4000. Good DACs, such as those found in decent quality AVRs, such as yours, long since surpassed the ability of human beings to differentiate between them. All of their significant parameters are below the threshold of human audibility, so don't be 'phooled' by 'audiophiles' who swear they can hear differences between one DAC and another - in blind tests, they can’t. So don't let that be a reason to spend more money.
TBH, used only as a prepro, I can't see any real difference between the X4000 and the 4520 in terms of performance. One may have more features than the other - IDK - but unless they are features you are craving, again it's not a good reason to spend money.
If you have cash burning a hole in your pocket, I'd look for better ways to spend it, where you may hear a real difference - speakers, subs, room treatments etc.
