Out of the LE's, H200's or CKS1000's, I can honestly say that I enjoy the ones that are in my ears at the time the most lol.
LE's are the most neutral, realistic and natural sounding. Nice wide soundstage. Slightly warm. Full sounding. Non-fatiguing. Sound awesome!
H200's are a bit more u-shaped.. Bigger, more impactful and more forward bass. More forward/detailed treble. Mids are not really farther back, but the bass and treble are more forward giving a more u-shaped effect. Very full and detailed sounding. Deeper soundstage. A bit more colored. But very enjoyable. Sound awesome!
CKS1000's even more v-shaped. Bass not as powerful as with the H200's, but still mucho bass, and it's nicely controlled and detailed. Mids furthest back out of the bunch (but still not recessed by any means). Treble most forward and aggressive of the bunch. Driest of them all. Very wide and deep soundstage with lots of air and space between instruments (most "open" sounding of them all). Sometimes more fatiguing than the others after extended listening sessions. Sound awesome!
So, they all sound awesome, and I can honestly say that I love them all.
