There's this stigma of isolation and "anti-social" associated with this hobby that I think may be a little superficial at surface level - think the one chair in a listening room and some of the judgment statements that are made. For some of us, the act of listening is deeply personal and perhaps even therapeutic. Others enjoy sharing music with others, which is just as great.
I don't know how much I've spent on my system, but it doesn't rival the experience and value of driving a motorcycle through small coastal and mountain towns in South Korea with entry-level Shure IEMs. I was completely lost in my early 20's and that time of soul searching and solitude, which included a run down motorcycle, headphones, music, and a foreign country really helped me figure things out.
Headphone, speakers, and components, they provide more than just music; more like small opportunities for some of us.
