Upgrade from hexa ?

I got the kiwi ears cadenza as my first , quite enjoyed their warm tuning until I got the truthear hexa as I wanted something more detailed and to try neutral tuning .

At first the hexa sounded bright and fatiguing but after getting used to it and listening back to the cadenza they sound muddy and muffled compared to it .

So now I think what I am looking for is something with technicalities and details like the hexa (or better) and with tuning that's kind of in between them maybe leaning against warm .

Also never tried planar , really curious about it so considering the letshuoer s08 or the arrti t10 .

So which one will suit me best the super mix 4 or planar or other recommendations ?
