Thieaudio Hype 4 vs Thieaudio Monarch MKIII

I just got the Hype 4 on sale. They sound good! I like them.

However, I don't want to collect IEMs. I just want one pair. Not the type of person to collect things. My question, how much better is the Monarch MKIII? I can still return the Hype 4s if I want, and I'm wondering if it's a big enough improvement to just go fully in and go straight to the Monarch MKIII.

There's going to be alot of people's opinion on this telling me it's all subjective, which, I know. I also am aware that as you get in the higher price brackets, the levelling up becomes more and more incremental.

Hit me up! Tell me your thoughts. Do I just go end game? Are the Monarch MKIII 'end game' worthy?
