Ins and outs of using home theater audio components for a computer? Someone help me

post #1 of 26
Thread Starter 
If you didn't read my other post, I am still considering the Klipsch Promedia Ultra 5.1 and the Logitech Z5500D speakers, however I just had a wonderful idea.....why not use full on home theater audio equipment for my computer?

I want to know, how this would work.
Which components will I need (speakers obviously, amp? receiver? etc.)
I would still need a sound card right? (getting a XFI Fatal1ty FPS)
How would the overall hookup look like?

EDIT/// Thought I'd edit this up here so someone might see it, but I just checked and my new XFI and the receiver for the Onkyo HT-S780s im getting both do have optical digital out/in puts. So I just want to be clear on this. Basically my hookup will go;

XFI in my PCI slot>XFI's optical out>optical cable>Receiver's optical in> and from the receiver, the speaker wires obviously go to their respective speakers, but I just wanted to be clear that the only connection from my PC to the speakers is 1 digital optical cable, correct?

Can someone please help me, maybe make a post saying that you are interested in helping me and ask ME some questions so I can better help you to help me get started? lol.
Analog or digital preamp? Btw, there's only 2 problems with it.....1) speakers are kinda large for desktop use unless you have a large desk 2) having TOO good of speakers can actually sound like crap. remember, your source isn't going to be all that great and revealing speakers won't be kind to a bad source....it'll sound very harsh

Well, by preamp do you mean my sound card? It would be a XFI Fatal1ty which has digital optical outputs on the 5.25in bay thingy so I guess it's digital?

EDIT/// if preamp means the amp for the speakers then I would want whichever is better so I guess digital?

No, by preamp I mean the voltage gain stage which is either a stand alone preamplifier or built in to a receiver. I'm guessing when you made this thread that you were picturing a digital receiver or integrated amplifier? If so, you would use the digital output of the X-Fi to the digital input of the receiver or integrated amplifier. Again, I kind of need a budget either for the entire setup or for speakers/receiver seperately. The price range can vary from affordable to more than a condominium.
Edit: after reading your above thread, i think you're going to want a digital receiver. While it's not as nice as a seperate preamp/amp combo, it'll be far less expensive.

How are these for a prebuilt? Also my budget is $500+any Christmas money I can muster so ~$700 BUT you have to figure in the XFI, so these are right in my price range, $399, i have the same set downstairs which my family uses for watching DVDs and such, only at Circuitcity, they advertised this as 1000W....could that be peak and the 750W (100Wx6, 150W sub) be RMS?

EDIT/// I just went downstairs and checked, my speakers do indeed say 1000W but not RMS or peak and they are the 2004 models which only supported 96KHz while these HT-S680s have 192KHz.

EDIT//// OOPS! These are NOT the speakers I have lol, I have the HT-S777B speakers which are quite a bit higher end lmao.

Those are the ones I have, note 130Wx6+220W does infact equal 1000W as advertised! That was RMS!

Ratings mean nothing in the audio world. There's no regulatory body, so you can't trust anything they say. It's handy to compare among the same brand,though. Just to give you an example, I used to have a Linn Klout that is 80W amplifier and would power any speaker in the world to it's limits, while a Harmon Kardon 2000 watt amp would blow up. (if HK even made one that powerful) Anyways, I won't get technical here, but if you're actually interested in ratings, you can PM me and I can go into extreme detail. Best way to purchase audio equipment is to test it in person and ignore everything written on the box. The best tester is simply your ears. All the marketing in the world can't make it sound better If you're happy with that setup, it would work fine with the X-Fi Fatality that you're looking at. You would connect either the digital output (optical or coaxial) of the X-Fi to the digital input of the receiver.

Sweet, so if anyone cares I decided to go with the Onkyo HT-S780 (thats right, 7.1 lol) and the XFI Fatal1ty FPS along with a 12ft optical cable. Woot! I can't wait.

Congrats! Btw, make sure you compare the optical output with the coaxial output. Even though you didn't order a coaxial cable, any rca cable with 75 ohm resistance can be used. Usually, a coax will sound better, but the optical has the advantage of not being able to pickup any electromagnetic fields or waves.
