Headphoneus Supremus
The term "musical" came about from a translation from Chinese of an attempt to describe a very slight difference between the sound of two different types of circuits, each designed to be "neutral" but slightly different all the same.
Must have been some sort of distortion going on.
With a speaker setup, the basic illusion of reality can be achieved. 7:1 sound, balanced response, clear soundstage, etc. and the room effects are the same as if the musicians were in the room performing. You're right, the room is part of the sound. With speakers you can have that. I've got piano recordings that sound so real, if I close my eyes, it seems the piano is in the room with me.
