Hmm.... I usually do not compare IEM with headphones.
The headphones I had were DT990pro, K240s, HD595, K601. I don't think livewires' sound stage would ever comparable with any one above.
(with AMB Mini3 or Ibasso D2, the two AMP I currently got.
Or mounted with a DIY CS43122 DAC with TUBE buffer.)
So, mostly I'd compare the sound stage of IEM with IEM.
For this matter, I think SuperFreQ got the same width as Livewires but with a little more depth.
The difference in quite small though.
No matter how good my FreQ sound is, I still think my HD580s are better in every aspect.
