Have been using for more than one year, no flaking, build quality or anything, basically great sound and accuracy.  forums can be useful but sometimes they are basically troll forums.  Price was too high, but didn't buy them to resell, bought them to listen.  Liked them better than my SShure...

Got a pair used from Amazon, nice sound, a bit tight on the headband, I thought the DAC made everything sound very nice, good solid bass, uppers a bit light.  Will post more with more listening.

Have really enjoyed the NAD sound but the comfort and fit are lacking compared to other similar priced headphones.  Albeit a small concern, it is difficult to enjoy a headphone when they pinch or cause headaches.  I would urge a higher price point headphone with more adjustment but same sound.

use a schist Vali with HE 400, sounds great.  Soundstream DAC

Must agree with others about cables, rather weird curve and feel to formed portion of cable, hard to configure to personalize, but comfortable.  

Just got a set of Primo 8 used on Amazon, must have been demos.  First impression is very clear and flat mid and treble response, bass is somewhat source dependent, but solid and not boosted.  Fit is good, nice amount of add ons. although for this price a non microphone cable should be included...
