I completely agree on the sound. It is great.
Which makes the glaring failing in build quality (and ergonomics) all the more frustrating, a bit like my old Alfa Spider.
It was a lovely looking car, great to drive, great for pulling birds, but it spend more time in the garage than on the road, leaked when it rained and broke down in the middle of nowhere, it was just awful. So I got rid of it and had a long legal suit to get me lolly back...
I have the same feeling about the HiFiman headphones... Love one, but don't care to litigate to get me wedge back when it turns out to be lemon.
