Thats called precision staging, imaging and layering, That should be how the great IEMs sounded. With m7/m9 I learnt that after years I after for larger, larger, larger soundstage but i was wrong. Soundstage doesnt have to be very wide or very large but they need to be precise, like a stage, like a room, but precise imaging and layering on another class will top the soundstage level. Even in andromeda I didn't find this stunning, until I have the M7, 1 of the greatest imaging / layering I've ever heard in my 10+ years journey in IEM world.
I completely understand what are you trying to say, its magical right? too bad I have to resist my buy on T800 because I already have m7 and bright isnt my preferences signature. When Audiosense throw another flagship with more balance and better technicalities maybe I will jump in to the club.
