To the OP: honestly, there aren't very many universals that are considered a clear step-above the FX700 or EX1000. I guess you could consider the W4, PFE232, and K3003, but it's all perspective and what you want to spend.
For me, I think the FX700 is absolutely amazing. So is the EX1000. So is the SM3. It all comes down to what you want from the IEM more than performance itself. I would be looking at customs if I were you, or cans. I'm really satisfied with the HD 25 1-II right now as I feel it combined a lot of the stuff I liked from the EX1000 (sparkling highs and amazing tonality) with stuff I liked from the FX700 (a -pretty- good timbre* and satisfying bass).
*I think the FX700 still has the best timbre out of any portable headphone or IEM I have heard. The HD 25 comes close, though.
