It's probably only a few of their highest end products and that doesn't really say that they are shifting production to the US. "The majority of our products are made in China - just like an Apple® computer." is what's on their website. That's really like saying "Apple is shifting production back to the US" just because they are making the Mac Pro here now, but that's probably the easiest thing to "assemble" here anyways. I am sure that even those Emotiva products that are supposedly made in the US, are merely assembled here.
For me Emotiva and Oppo are kind of "Brand names" focused on design. Sure they may have some advanced chips and things, but they appeal more to consumer audio/video. Their designs are very similar and generically modern looking to me. It's the kind of stuff people buy when they don't want to research something better because it's somewhat affordable compared to the boutique US makers (of course at the cost of US jobs). They just look like cheap mass produced Chinese products that are supposed to look cool to most Americans. Not my cup of tea...
Schiit on the other hand doesn't just "assemble" their products in the US. Everything from the chassis, to the boards, to the assembly, all goes on here. They hardly use any Chinese components in their products - those WIMA caps are made in Germany, Alps blue velvet pots are made in Japan, Dale resistors made in the USA, etc... On top of all this, the Schiit designs are modern/futuristic and very minimalist in nature. They are some of the most beautiful amps/dacs to behold and I don't think they will ever go out of style.
This is why I respect and admire Schiit so much. Even though their total production is in the US, and they use top components, and have excellent sound and build quality and design, they still keep prices low. As many have mentioned, they could charge more, but their goal is not to inflate prices. They are one of the few brands out there that really, truly care about their customers and about what they do more than about stuffing their wallets.
