Ha ha. Welcome to Head-Fi, and...
I still keep trying to get it down to two: one for classical (most of my listening), and one for everything else. OK, maybe three: one for jazz, one for rock...
Can't speak to Atticus / Eikon but just reveived my ZMF Omni's and they are stellar for classical music, especially solo keyboard which is my preferred genre. I'm hearing counterpoint / bass lines in Bach more clearly than I ever have but never at the expense of euphonic mids and extended, non-fatiguing highs.
I'd love to hear your thoughts about Zach's new dynamics for this type of music as well.
