Is it true that non computer speakers are much more better quality than computer speakers? Which ones should I get to hook up to my Auzentech prelude? (Is it hookable to it? Do I need speacial cables?
These days, if you get some name brand speakers (Klipsch at the top of the list, then Logitech, then whoever) I'd say you'll be doing just fine. The speakers that these companies create that are designed more for multimedia/computer use are still based on proven speaker technologies that have been around for decades now.
Klipsch IS a speaker manufacturer, and they have been for a very very long time now, so the addition of multimedia/computer speakers to their lineup of frequently rewarded loudspeakers in the "Hi-Fi" and audiophile communities is near legendary. The ProMedia series of Klipsch speakers effectively set the bar years past with the first 4.1 system introduced around 1999 or 2000. Since then they've just improved the quality with each new revision and even their 2.1 system (which I'm a proud owner of) simply has to be heard to be believed.
Logitech is doing really well in their own speaker manufacturing nowadays, and they get a lot of rave reviews for their products. I'm still a fan of Klipsch however and I can spot the difference(s) in sound quality between Klipsch and Logitech systems with my eyes closed.
Aside from those two, the only other name brand of consequence for multimedia/computer speakers is Bose, and while they have some "nice" products, personally I wouldn't recommend them. The price is ridiculous for what you get, even with the Bose name attached. They just charge entirely too much money (personal opinion here, so be warned) for their products which typically get reviews that place them well below Klipsch or even Logitech when we're talking about the multimedia/computer speakers they make.
There are tons of low end speakers, some name brands like Labtec, Altec Lansing, and others. But the top tier stuff strictly designed for multimedia/computer purposes are those three: Klipsch, Logitech, and Bose.
Outside of that, you'd step over into the "audiophile" or professional speaker categories. While I could go on about those, it's been about 15 years since I was seriously involved with high end hardware on the audio front - meaning the kinds of speakers that usually run in the low 4 digits for cost range. I gave that stuff up years ago when I finally came to the conclusion that most if not all "experts" in the realm of sound don't know anything at all and their ears aren't much better than mine.
In the long run, only YOUR EARS and what the products sound like to YOUR EARS are what matter. "Best" in any situation is a purely relative thing because, especially with speakers, it's not the speaker that really matters, it's your ears and what the speakers sound like to you. Sure, you could read reviews, even read my post or others that will follow and decide to purchase Klipsch, or Logitech, perhaps Bose or even some other brand, but in the long run, if they don't sound good to YOUR EARS, then nothing anyone says matters.
I own some Klipsch Promedia 2.1 and I like them. They have a great sound for such a small package. They are not nearly as good as my B&W 603's (large, 50 lbs each) but that's to be expected. New the Klipsch can be found for under two hundred dollars (probably way less than that now), new the B&W go for over a grand..and you still need an amp with that.
They are two completely different beasts. Unless your budget is over $$500 dollars or so I wouldn't even bother trying to go with real speakers and stick to computer media. If your budget is much larger, definitely go for some "real speakers".
