The snob accusation is usually born of envy which is pride manifest. Ignore them.
As far as audio gear is concerned unless you are uber rich- the 1/100th of 1%ers you probably don't have $100K speakers with $10,000 cables hooked to three $35,000 amps fed by a $70,000 front end all interconnected by $20k of custom XLRs. in a $250K listening room. The rest of us have to research, shop, budget, plan, search, buy used, etc and slowly build our dream system while making a mistake or 3 along the way,
BTW, I know a few billionaires. The kind that made their own money and the kind who inherited it. Most are very interesting, and down to earth. It's the poser wannabe jerkoffs that act snobby because they think that's the way rich people act. They can't be fixed so ignore them.
