The problem with niche headphones like the ZMFs is that there’s so few of them to actually audition, so most people are buying off reputation or reviews. You can only guesstimate if a headphone will suit your taste by reviews, and for a TOTL headphone, if it’s not ideal, you have to sell and move on while it’s new. I don’t know of anyone in my country (South Africa) that has heard and actual Atticus (or Eikon), and yet the Atticus is the only candidate on my list to replace my Fostex TH-X00 should I decide to sell it. I know I love my Fostex, but I can only go on reviews and subjective opinions as to whether or not the Atticus can adequately replace it. No doubt it’s a better, bigger, more refined headphone, but that doesn’t always mean it can deliver the same magic you’re used to from a particular pair of headphones you already use and know.
PS. As for the Teak vs Eikon comment, I can somewhat understand that, given how much more bass emphasis/quantity the Teak has vs the (based on reviews) more neutral Eikon. That’s why I bought an LCD-2 as a complement rather than replacement to my Fostex, and likewise would consider the Atticus a complement to the LCD-2. If I bought an Eikon it would likely overlap or replace the LCD-2, and frankly, nothing is going to replace my LCD-2.
