I also had a bad customer service experience with Schiit.
NOTE: if you buy a used Schiit product, there is no warranty at all.
I bought a new-in-box Freya + on USAM. The tube section was unbalanced. I called Schiit to ask what the proper approach was to find out if a tube was bad. They told me they couldn't help me because their policy is that their warranty is not transferrable and this was a warranty question. I said, I'm just looking for information. Sorry. Can't help you. But you can buy a new set of tubes for over double the market rate. Lesson learned.
