FS: A pair of ready to roll C84 modules

I've got a pair of C84 modules I'd like to sell if anybody is interested. My chassis is full and I'm not doing as much classical work as I used to, so it's time to swap these out for another pair of A12s. I'd like to get $500 for the pair, but would split them up if there's interest. I've been using these for about 9 months without any trouble and they sound great.
