May get the box at some point, but I'm more than happy with the 3CD set for now.
It kind of bothers me that I had to box up some of my original US Atomics to make room for this on the main Rush shelf so I don't have a CD on the shelf with the original cover art, but it's the best sounding Kings CD I have.(Can't exactly pull out the Mobile Fidelity 2112 or the two 2112 deluxe editions because of the live tracks from 1981 Edmonton on one and the alternate Massey Hall tracks on the other.)
I haven’t reconfigured the CD rack yet. Just the LP shelves for the box. My Rush CDs’ use about 30 inches of space in my CD rack so I know where you’re coming from.
