Sometimes the music reproduced on our systems is so real you can touch it.
What creates the touchable illusion?
We know a pair of earbuds or a boombox doesn't come close.
Even live music doesn't always evoke the same sense.
I think it has two requirements: a quiet environment and great components.
I can stir the sense of touch only if there are few audible distractions. Like what we often achieve in our listening spaces, or hear in an intimate live venue.
But even the quietest of spaces won't beckon touch if the equipment isn't up to the task.
If your system is touchable, you've done well.
