IEM recommendations step-up from P2/L3/Starfield

I’m currenty thinking about further stepping up my IEM game. I currently have:
Tin P2,P1,T2 // Thieaudio Legacy 3 // BLON BL-03 // Moondrop Starfield // Monoprice Monolith M300 // Soundmagic E10s

My portable gear is
Dethonray Honey H1 // Chord Mojo // Little Bear B4-X // iphone // Qobuz

I’m currently thinking about adding another IEM like the Thieaudio Clairvoyance. The question is: would the audible difference be worth it? How about diminishing returns? Would this be a huge step up or do i have to aim higher, like UM MEST or Sony IER-Z1R?

Next you’ll ask, what my sound preferences are. To be honest: as long as nothing is piercing, i’m open to different tunings AND, what’s more important, i have the ability to change the characteristics by changing the source gear. That way i’m able to get enjoyment of everything i have, including P1 und P2…

Thanks for the feedback!
