Call this a model. And it may be a bad model for some. BUT: a bad model is better than no model at all. It makes us think and stimulates discussion. I do have two "pricier" references, the ones I would take to that famous lonely island with me. The first is the UE900S, a 4 BA earphone, which I got from "Drop" for $179 (MRSP $399). This one is my reference for resolution. The other is the JVC HA-FDX001, a single DD at $250, which is my reference for timbre (also from Drop). However, considering the blistering fast progress in technology, the incredibly large market selection, and the lack of organic sound/high harmonic distortion in BAs, I'll rather wait for that "kill" once I am 200% sure, it will be the endgame. And these JVCs are my personal endgame in terms of dynamic drivers.
