As with many of us, my family and friends have no idea what my stuff costs, except my brother who thinks I'm nuts. Although he will be the first to say it sounds great .... and he is often the recipient of nice audio hand me downs
I really don't want them to know, and if anyone asks I am evasive and change topic. It's nobody's biz....
I think if you have any common sense you can look at some of this gear and know it's not cheap. My buddy has a pair of downhill mountain bikes that cost $7500 and $8500, so it's all relative...
