Yes I tried my Atlas on balanced with my WM1A but I had to use the SPC Litz 2.5mm cable with Fiio BL44 converter briefly. I did not get any 'uplift' as I expected. I mean the sound is just as good but I was as 'wowed' as my 64Audio U4-SE with EA Eros II cable. On that IEM going from SE to Balanced (with the same cable) I could hear an instant 'uplift' in audio performance (e.g. wider staging, more accurate, tighter bass, more extended trebles, just more impact). I know it isn't volume because I roughly matched it by my ears. Back to the Atlas, I am reserving my judgement until I can get a pair of silver Litz on 4.4mm. Or maybe I would reterminate mine. I enquired my local store and they would check with their suppliers/CA. I'm due to be in Japan by year end so I will be researching on a good pair. Speaking of which has anyone have similar experience on WM1A? Also what would be a natural cable upgrade for the Atlas? Would that be Reference 8 or SXC 8? Or perhaps go for full silver like the stock cable?
