What were you used to listening to before the Layla? This matters a bit as your impressions depends on iems you were used to in terms of it's stage presentation. Because I've owned the Layla in the past, and I wasn't particularly moved by it's spaciousness as I've owned the NT6 prior to that. This is all by memory though, but I can't recall what was so impressive about it(I don't recall particular attributes that really stood out for me).
I'm recalling purely by memory as well, it sounded really natural and organic, the separation and stage were what got me the hardest, it felt like listening to headphones.
Prior to the Layla auditions, I was pretty much listening to the Fidue A83, TF10 and UE900.
