From $99 and up, audio component manufacturing is returning to the U.S.

We don't manufacture TVs, computers, cameras, or phones in the U.S., and American audio companies have been outsourcing production for years, but it's starting to come back. Not just for ultra-high-end products -- Schiit Audio's $99 Magni headphone amp and $99 digital converter were designed and built here.
