Thanks! So a few points:
RK3188's have a default clockspeed of 1800MHz. However the actual proper clockspeed for the FiiO will depend on the other passive components on the board. FiiO downclocked the max speed to 1416MHz however I've found that quite a good range of these players support clockspeeds of 1704 and even 2016 (some can get even higher but they are very rare to find).
Fidelizer is easy to install - the developer has created a great update.img that you can install just using the normal FiiO windows tool. However you'll probably need to reinstall twrp and my kernel again on top of fidelizer. I don't recall if the latest version (1.2.5) overwrites all partitions but let me know if so!
