I did tried the A&D KS3 i would say its decent but its not their best work yet, after I compared this to FLC8p i would say the FLC8p has better sound quality overall but i wouldnt say the KS3 is sucks - i would say its comparable to King Pro

Well, i'm happy you find them decent....but im confuse about the ''best work yet'' sentence. And even more about the fact you prefer a 350$ earphones...everybody is subjective, but here, its just plain, well....confusing. I tried them a full month by the way. And I adore D6. But yeah, I prefer how well balanced the KS3 are.
