If they weren't made in East Asia wholesale, then the parts most likely came from there and they're just assembled in the US (or elsewhere). There's only a very small handful of companies that don't source SOMETHING from Asia (Dynaudio in Denmark is one, but definitely doesn't have much company.)
I know from a quick search your Blu-ray player came from Malaysia, which is fast becoming China South in terms of manufacturing. Same with my Onkyo amps. McIntosh still assembles in the US, but the guts come from elsewhere.
Electronics are almost impossible to build in the United States anymore. China/Asia not only has a lock on labor, they also have huge deposits of the rare earth elements needed.
Don't believe everything on the Interwebz! A duck's quack DOES echo!
