My soundstage create also imaging filling the room in some recordings more and in some other less, and an intimate impression like in my 7 headphones and better...I will neverr use them anymore...The sound is near me like with an headphone but in the room out of my head and disconnected from the speakers complketely...
If there is any connection between the sound and the speakers, your room is not under control...

Acoustic is Queen and key...
