My friends take long listens, close their eyes, nod, agree it sounds marvelous, but still think its crazy to "waste" so much money on that gear. Seeing I'm 21 and only a student, they may have a point, but as music is the most important thing for me, money will certainly not be an obstacle to my enjoyment of music.
They usually simply come in my room, wonder and ask what my gear is all about, I explain quickly, give them a listen for 10-15 minutes usually, watch a smile on their face as they listen to their fav tunes in extremely good quality, and thats that.
Either way, I'm not really interested in hearing my friends tell me how great my rig sounds and how right I was to buy all this gear. First of all, I don't feel doubtful about spending so much on all of this, I loved it and still do, no doubt in my mind so why would I need confirmation?
Second of all, as long as I am able to hear the differences between equipment and overall sound quality, wether they're able to or not isn't my problem, its theirs, so why would I care? I enjoy my setup, too bad if others don't, they're not the ones who spent so much on it and I shouldn't really care if their opinions differ from mine, as long as I enjoy my rig thoroughly as I do today.
I think people who actually bring importance to other non-audiophile people's opinions about their rig are more into this hobby to have a hot looking collection and show it off rather than for the great sound such rig can get you. It's not a matter that I've ever thought about until I found this thread.
