Dudes.. what? Do any of you know anything about stereos?
OK, first things first: do NOT buy your stereo from a general home electronics store. That means if a sales person has the ability to go from washing machines or TVs to sound systems, you do *not* want them selling you a stereo.
Instead, go to a hi-fi specialist. One with a lot of brands that you may not have heard of. Talk to them for a while. Explain your needs and budget. If it sounds like they're switched on, let them continue with recommendations. If they're snooty and talk down at you like you're a pleb, move on to the next store.
It's likely that you shouldn't buy a brand that you see in most loungerooms, as a general rule. Don't buy Sony gear. And all the rest like it.
USE YOUR EARS.
Also, check that the model's assembly has not been outsourced to a cheaper centre. Many high-end brands are getting their cheaper models assembled in places like China and the quality can be substantially worse. Try and work out where your stuff is coming from.
OK, onto specifics:
* The amp is more important than a lot of people here are making out. Make sure you get a good one. If you don't need surround, don't get surround. It's a waste of money and it costs a *lot* to get right. The amp should probably cost nearly as much as your speakers.
* If it's CDs you'll be playing ensure that you get something with a good DAC. Ask what the CD player has. Do some Googling of it and see what the reviews say. If you play vinyl, that's nice, but for crying out loud guys vinyl does not immediately equal "good" you need a good turntable and a decent preamp. A $30 jumble sale record player does not sound better than a CD. sorry but it doesn't.
* Finally, speakers. Read your reviews. These are likely to get outsourced, so do your research. See what other people think but THEN use your ears. Really, it's a taste thing, so do lots of listening (with your own music) in the store and see what works best for you.
Make sure you match your speakers and amp. Probably let the salespeople know what you're hooking up. Don't get something more powerful than you need - if you're in a small room, 75-100 watts should be heaps. If you are or will be living in a big place, maybe you'll need something bigger.
I don't know what hi-fi values are in the US (I'm in Aus), nor do I know what the supply situation is like or who gets distributed there so unfortunately I can't suggest brands. If you're wondering, I have an NAD C372 amp and C521 cd player (which I am really happy with), and an older (but pretty great) Pioneer PL-6 turntable and Jamo E875 speakers. Just FWIW...
