I'm pleasantly surprised to find fellow audio nuts here on MMM--I've been quiet up til now because I was pretty sure it was the kind of expense you'd get facepunched for. :P
If I had to categorize myself, I'm a budget audiophile? Maybe? I have three different music setups (living room, bedroom, computer office), which is a bit ridiculous given the size of my condo. That said, I love music, am listening to it constantly, and while I have some nice headphones, I don't like being tied down by a cord to a stereo.
I will say that if you're smart, patient, and do your research, you don't have to spend a lot of money to get truly spectacular sound. Most of my system are good solid brands/performers (Harmon Kardon, Cambridge Audio, etc), and for most of them I paid $100 or less via Craigslist. You just have to know when to pounce on a deal. The only exception to that were a couple pairs of speakers that not only sounded amazing, but had a beautiful rosewood veneer--I will admit I paid a bit extra for those because they were just too darn pretty to pass up. :)
That said, if you don't care that much how your music sounds, then there's no need to invest the money or the time into piecing together a system. I just find the challenge fun, myself.
