I don't think B&M stores are going away, precisely because many consumers prefer them as they need the expertise a salesperson can offer, and the ability to compare brands in a sound room.
As for the Chinese manufacturing throwaway products, tell that to Parasound, Adcom, Sherbourn, NAD, etc. Guess where the new line of Anthem AVRs is made. It may have been the case 15 years ago, but not now. Most manufacturers have products or components in their products made there. Like Japan did, China has learned how to make quality.
