Hi, I'm new to posting here, but would like to voice my humble opinion here, as I am a bit different than most of you.
I consider myself an audiophile, but I would never tell anyone else that in person. This is only because I believe the term has a negative connotation. A connotation involving one spending ridiculously large sums of money on equipment and being completely impractical. I am not saying anyone here is like this, that is just what I don't want to be viewed as when people find out about my interests in audio.
I am only a senior in college, but am up to my ears in all of this. And I only started 3 years ago. I now work at Event Services, a campus job where we setup equipment for all the events going on on campus. I run sound at concerts once or twice a week, and do so with a passion. If something does not sound right I won't stop until it does.
I can't even to go a concert anymore without constantly critiquing the sound. I often feel like kicking the guy behind the sound board out and doing it myself. I swear some of those people don't know the difference between sibilance and feedback.
I spend a lot of my spare time reading audio forums, tuning my car, and planning my next project. Well...I don't really have spare time. Between full time classes and an average of 30 hours of work every week, I don't sleep much.
I have a driving thirst for knowledge in all aspects of audio, from home theater and car audio to live sound reproduction and recording. I know that I can never know it all, but I'm trying my best.
I do everything as DIY as I can. Mostly because I want to know exactly how it works and why and I like the pride of knowing I did it. And how else could I afford it all as a poor college student

I know my "home theater" system is terrible right now. That's why I just bought Crown amps and a new Marantz receiver for a pre/pro. And that's why I'm spending winter break building a center channel from scratch (from a plan someone else designed, I am still learning about crossover design), and will be building matching mains and surrounds when my income allows.
I know my car's soundstage is low and the bass lacks definition. But I spent countless hours of my time this summer/fall searching for deals on old school reliable amps and installing everything myself and tuning to the best of my ability. For me, tonal accuracy is more important than spatial accuracy.
Sorry about that long introduction/rant.
I believe that a true audiophile is one who has a passion for sound. One who has the drive to learn as much as they possibly can about all different aspects of acoustics, audio gear, and the audio market. One who strives to improve their personal systems to sound a certain way, whether that be identical to a live performance, perfect imaging, or clean and accurate.
