From the product page:

" When XMC-1s are traded in by customers for our newer Atmos based processors, they still have many years of service life left in them for use in movie and music systems. In light of that, we've created a new recycling protocol where we carefully inspect, refurbished, update, and renew XMC-1s. By giving the XMC-1 an Act Two (movie reference since we're home theater geeks), we've found a way to be more sustainable and eco-friendly, while at the same time provide customers another incredible audiophile-quality AV preamp processor choice."
