I think art work whether it be paintings or sculptures improves the looks of a room and gives the mind/eye another avenue of occupation. Real or artificial plants are always a plus viusally and sonically. Also the room will look better with more furniture than two speakers, a rack of equipment, and one chair. Book cases, record racks, storage/display niches and of course some artful lighting. Some of the photos of rooms I've seen make me glad I don't listen to music in that room. They are just so bland and boring.
