Of course you need the light box- I believe I am at the apex of diminishing returns with this system. I swapped out PS Audio Statement power cords for manufacture's stock cords and Nordost Blue Heaven interconnects for Audi Quest Golden Gate because I got tired of fighting cables. I use AudioQuest Rocket 88 speaker cables. I believe in good cables, but I'm a member of the snake oil church. Thanks for commenting !
