A brand or two may disappear. But I would not expect audio Armageddon just yet.. Some brands will continue under new ownership (like McIntosh). As an aside, it appears that Bose is going to continue to let McIntosh be McIntosh in terms of design and build. I think that is good news.
I prefer to buy American when I can (my DAC [Musical Fidelity] is made in China. Most of the rest of my gear is U.S. made [PS Audio Amp; Aric Audio Pre-Amp; Magnepan speakers; Audeze headphones]
I don't dis folks who buy Chinese made audio. Most of the more affordable gear, and much of the higher end gear is made there. However I don't wring my hands over the fortunes of companies, particularly American companies. that manufacture goods in China, because they can get away with paying the workers there subsistence wages.
