If you’re listening through headphones then you can toss out the room and it’s all up to the equipment.What do you think the shell of a headphone is?
A ROOM.... Most of the times a bad room... a room with hard trade-off that you can modify and control better with damping for example.... i modified with success all my headphones because they were all unsatisfying...
I trash my 7 headphones in a drawer: 2 stax, 2 dynamic, 2 magneplanar, one hybrid.... Only the hybrid one has a good timbre recreation but other limitation....
My room now is SO good at 2 locations for listening thay listening to headphones is unbearable....
Some years ago it was the opposite, listening to the same speakers was unbearable at times because of his limitations... in fact the problem never were my gear but the 3 noise floors uncontrolled: mechanical electrical and acoustical....
