I suppose my title's caption, 'a touch of class' foretell my conclusion of the e-Q7. It is without a doubt, one of the most impressive earphones on the market. I don't really care what's under the bonnet here, but I'm sure it was a labour of love. One thing's for sure, it doesn't sound 100% like your traditional balanced armature and it certainly isn't as powerful as a dynamic driver.   For full review and pictures, go to my review of the ortofon e-Q7.    Since headfi isn't as much into construction quality or ergonomics as it is in sound...
