^ No, not really. My J3 does not power it well and its no slouch in driving potential, on 35/40 volume its just in the realm of normal listening and lacks staging qualities, it needs an amp which I am not happy about. The E10 is not that well suited for its sound qualities, its stage is limiting it and makes it sound really off and boxed, and odd sound. A better amp is needed not only for stage qualities but also driving power. I do not think the E10 is nearly powerful enough for it which is why I listed my FA011 for sale. Also, my Livewire duals make it sound muffled as will any great iem $250+ so I feel you on that, but that doesnt make them a bad value, despite that, they remain one of the best if not THE BEST sub $200 headphones on earth.
