I had a similar experience. My stands are 13 inches high. I was doing some housekeeping recently and had occasion to place a cardboard carton of LPs on the floor between my floor standers immediately in front of the electronics stands. The improvement in soundstage and detail was obvious and immediate. Strikes me it was the equivalent of placing electronics closer to the floor. Mysteries of acoustics. My wife won’t let me keep the box there, but I’m going to experiment some on the basis of the improvement I heard.
