I second this. Elite was my daily driver for two years before I got my Caldera. The angled pads improve clarity, depth and detail retrieval massively on the Elite. Once those pads came out, I never used any of the other pads on the Meze. Both are fantastic headphones, but quite different. Elite is a lot more spacious with taller and larger soundstage, and a lot more laid back, softer sounding. Caldera is more energetic, more dynamic, the soundstage is smaller in comparison, but instrument separation is even clearer. Instead of the Elite's big, warm bass, the Caldera offers more punch and dynamic impact which I definitely find more enjoyable with EDM. Also, while the Elite is one of the more natural sounding planars out there, still can't reach ZMF timbre and realism when it comes to vocals or acoustic instruments for example. I imagine, (lower) treble energy can be too much for some on the Caldera and make them choose the more laid-back Meze, but most people can balance that out with the thick pads, or if has to be more extreme, with the mantle mesh.
For me the Caldera edged out the Elite with its even more organic sound and more weighty, dynamic and impactful presentation. I think, the choice between these two ultimately comes down to whether you want a soft, smooth and relaxing listen or a more exciting, energizing one.
I also have to add, that initially it took me a few days to really appreciate what Caldera does so well. There are pros and cons with both headphones. But once I truly understood the strengths of Caldera, I was lost forever.
