Nothing glamorous. I live in an apartment that has cardboard walls and always play with headphones.
It's an N3 (not the X). To the right is a slide-out drawer with the laptop I use for VSTs. In the cabinet below the laptop is the Focusrite interface and other junk.
The speakers are just for media on rare occasions. I don't use them for the piano. (Which, as I said, is headphones-only.)
