Last time I bought speakers before this was 2007! Last TV was 2013. Previously I'd managed to run a pc made of second hand parts from 2008 to 2017 with no upgrades.
I think you are correct in a way. I do like the TV and sound bar. But also I'm wary of the addictiveness of reading reviews, upselling myself to higher specs and higher price than I'd originally intended. There does seem to be some sort of dopamine hit with researching options.
