Snob is in the attitude not the knowledge or the hobby.
I see it most here when (1) someone is telling another that their system isn't resolving enough or that it needs to be upgraded to meet their projected requirements (or worse, to win some argument), or (2) people drop names of gear simply to show they can afford something your average 'goner cannot.
They think it affords credibility when really it's the person who can't afford the 5-figure stuff and works to get their system sounding just as good that deserves the credibility.
However certain hobbies do attract some snobs.
On Schiit - I have a Gumby and although I have DACs that cost more (not a lot...don't have enough money to be a #2 type snob) I really like how it sounds and use it most. I think it's good gear for the money.
