Looking to purchase a new iem with a huge soundstage (good width and depth) with airy and forward vocals/midrange sort of like your sitting in the front row seats in a concert or on stage. Currently i'm using the E-Q7 and CK100 as my main iem's. So I wish this new pair to atleast match or surpass them in terms of details and clarity. In terms of bass I prefer it to be neutral. I would like my treble to have good resolution/clarity with some sparkle but never harsh or sibilant, and also well extended. Also I would like the iem to have good imaging and instrument seperation. I mainly listen to Japanese music and the genres I listen to is really diverse - rock, metal, female vocals, jazz, instrumentals, post rock, math rock, shoegazer, experimental, pop , hip hop, rap, r'n'b etc.
the iem must also be comfortable and have good isolation because I will be using them on my commute.
My source will be the Z1070 but I am also thinking of purchasing the new F887 Walkman.
Currently I'm looking at the Heaven V and VI by FAD but other recommendations are welcome.
