Firstly, it is apparent that earthborne vibrations affect *every* component, line conditioners included. It is also apparent (with some testing I've done over the last year or so) that footers and different platforms affect the performance of a line conditioner, especially when 'mated' against the chassis itself. Differing products such as maple boards, bamboo, Black Diamond Racing pucks, Symposium shelves, and other constrained layer damping products work quite well. What someone ultimately chooses is a matter of personal preference....but they all work synergistically with the chassis, and improve the sonic performance.
