Guys, I have been lucky to finally hear both. Zeus is still on the market, because it's sooo good at what it does best. There have been more 2 channel guys/gals, like I am, on the boards lately. I like a few of the IEM's that I've been sent and heard. Here is my take on the EE TOTL IEM's:
Zeus is like a GREAT Planer speaker (Panel type) like a Quad (UK) or Magnaplaner (US)
Legend X is a HIGHLY dynamic, cone driven speaker like a Wilson (US) or Magico (US)
Phantom is like the best of all worlds like a Vandersteen 7 mk2 (the best speaker I've personally heard in the world)
What folks need to keep in mind is that any designer, regardless of cost, has to make compromises. They make them based on what they feel is best in the price range they have to play in. The is for any component in audio as well as cables. When we read folks interpretations and thoughts on gear, we all to often take it as an absolute, but it's not. There are variables, like what do our own ears tell us. That is huge and it's why some feel something is bright and the next posters says the opposite.
I personally have not engaged with many of the IEM's that have been sent my way. The same goes with cables folks have sent to me. When you guys go out to audition or are on the tours, I bet you don't love everything that you read great things about on the board. You have different tastes and like different products. It's what keeps everyone in business or not. Again, not trying to upset anyone, but these are my opinions.
