Sorry, but for me, Aurora has muddiness in the sound. I have to reduce the low mids in 2 dBs to avoid that muddiness that makes the sound a bit bloated and slow. I am talking about myself. You can hear different, of course. And I am not saying Aurora sounds bad... I am only speaking about the things I don't like about the Aurora, but I think it sounds OK, extremely coherent. It is the #13 in my ranking list.
And of course the NP is not the only one in the range with the treble I like. I like a lot of IEMs with great treble energy like Monarch MK3, 64a U4s, KSE1200, Timeless, S12,...
And I am not saying that having tame treble means no details. I am saying that Aurora has less details than NP, and less treble than I usually like. I am talking about Aurora, not any other, and of course not Alita (I haven't tried Alita).
