I'm frustrated with people who don't ...

Sorry for a long post...
Recently I was at a 3-day meeting out of town for work. For an evening activity we had a cook out at a colleague's house. While there, we gathered around his deck and a small fire in the back yard. I found myself in a group of 6 guys discussing hobbies. I mentioned my love for audio and began to describe my system and music library. Almost instantly, I was "pounced" for believing that any "hi end" component is worth the money compared to anything else one can buy from Best Buy. "Digital is digital" one guy stated, "an $89 player is as good as anything else out there". I attempted to defend my position but in no way was I able to convince anyone. I told them the next time they're in town, I'd have them over to my place and let them hear the difference, but I know most will not acknowledge the quality of sound. Footnote: I've known these guys for 3-5 years and they are professional level headed guys, I wasn't bragging, I made no grand statements that my system is better than anything else, I just talked about my interest and brought it up when they asked me. The icing on the cake was their disbelief that my system can only play one CD at a time... "you don't have a carousel on your CDP?" Man, I was frustrated.
