I fail to understand the harm it causes? The crapy/misleading marketing that many manufactures do mabye. I don't disagree with many of the points made. It does require a room and space to dedicate to speakers, etc and is not convenient to set up. There is definitely an elevated cost required for gear/ speakers etc. I don't think anyone can argue those points. I look at it purely from does it enhance the movie/entertainment expereince? For myself, and many others who have set up it correctly, I would say yes. As discussed in an earlier post about Another Life on Netflix, waching that series in Atmos definitly enhances the expereince.
Audio is more of a passion, than hobby for those who frequent these sites, so I would not say it has caused more harm or a disaster. It has a more select audience who have the space and want to make the investment.
"Atmos is a huge success among the ultra niche that frequent sites like this, but we represent an infinitesimal amount of the buying public."
I don't fully disagree with this, but 90% of what we talk about even outside of Atmos is still niche and for most people outside of these site, you will find soundbars, straight TV sound or cheap kits. So that statement can apply to alot of things outside of Atmos.
