These might show up as a returns (under the 14 day trial) on a discount on their "B-Stock" section from people that found they didn't work in their system: https://www.schiit.com/b-stocks
"What is B-Stock and Closeout?
This is a place where we put all the stuff that doesn’t meet our cosmetic standards, or is returned from customers, or we found while cleaning out the shop (no kidding.) Everything we sell here is covered by the full factory warranty. However, all sales here are final. There’s no 15-day return period. There are no trade-ups. If you know what you want, that’s great. If you may need to try a few things, better to go with the regular product listings. "
They don't sell repaired stuff in this section. I've gotten some good deals there.
