OK, let me rephrase that a little bit...with a top-tier IEM you are getting an IEM that does something better than any other IEM, and everything else that is nearly as good. So if there is something you think the W3 does better than any other IEM, that is top-tier to you. But the whole idea is that people think the IEM they have might be top tier, but something else does most of the same things, but better. Therefore that now becomes top tier.
And as you can see with the updated first post, I am including IEMs others have suggested even if I don't agree. And again, in the first post there are some other thoughts on what top-tier means to various people.
