My B Stock Modi 3+ arrived in Ohio much quicker from Texas than the A Stock that shipped from California. (Travel time only, not counting the long wait for the A to get built). The California version spent three days in California after leaving Schiit's hands. The B stock looks great, as good as the A stock. It came with all the cords and other bits. I will try it out later today.
Edit: Four songs played, sounds great. If there is a burn-in period I cannot detect it. Perhaps as a B stock some previous owner burned it in, I wonder if it was burned in with classical, rap or country?
