Lots of negativity in this thread, we should lighten up a bit.
People have less disposable income, so they will spend less on luxury items, hence the increase in sound bar sales. This is not a bad thing, it is a good thing. It means people are still spending money on audio products.
Perhaps when they have more extra cash, they will upgrade to better things.
Earbuds and the like are the perfect solution for young people. They are affordable and portable. This is a good thing since it means young people are putting some priority on listening to music.
Music is meant to be shared. Earbuds are not a permanent solution, since people will want to enjoy the music with others, some of them will want it sound better, some of those will want it to sound much better.
The point is that people are still spending money on audio, and are doing the best they can. When they do better, some of them will upgrade. I honestly do not care if the AVR brands mentioned die. My newish $1400.00 Denon is feature rich and quality poor. They deserve to go out of business imo.
