I run mine balanced, but on the low gain setting of my amps. I am also pretty careful with the volume.
Balanced from the Audio-GD NFB-1Amp here; works like a charm! Haven't noticed any downsides yet. Balanced the imaging seems a bit better and the bass is tighter; but really by a small margin.
That seems like a very logical reason, although I kinda wonder if not including a balanced cable has gimped these in some way, because so much high end source gear is designed around balanced. A lot of reviewers are comparing these on unbalanced through a bargain bin source to competitors running on balanced on a preposterous $3000 tube monstrosity of some kind. Or they're comparing them on an amp designed around balanced but with its inferior-sounding unbalanced port.
I ran mine balanced with my Jot with low gain and the volume pot around 11. I'm not sure if that was the reason or not but a week after use, my left driver went dead
I've already sent it to hifiman for an out of warranty repair but it was just extremely unfortunate. I'm trying to single out the point of failure and that was the only reason I could guess it happened.
