I might sound stupid. But here it goes anyway. I am tired of changing formats for Home theater audio, video formats, disk standards. Too many moving parts and it seems to be hard to keep up with.

I am thinking a plug and play might be a good way to keep up with. I have a old integrated receiver that i need to replace. I am thinking of just using a HTPC for it. Because all audio files can be in HDD instead of CDs, DVDs, Blu-ray, etc. Same goes for Video(mpg, divx, vob, etc...). Using good video cards and audio cards shouldn't i be able to connect it to say a amp?. Amp will drive my floor standing speakers. HTPC will act as pre-amp if you will.

has anybody tried it/thought about it? seems like, if any new stuff comes along, it is just a question of changing that particular card and you will be fine.

what kind of recommendation you have if stick with just stereo? if it is 5.1 what kind of amp?

thanks for your help.

There are no sound cards available that can put out enough power to act as a preamp. You will need a real preamp to feed the amp. Most sound cards will not put out enough power to power a set of headphones.

The idea has been tossed around lots of times but no manufacturer has stepped up and made a true preamp/processor sound card. Until that happens you will need a preamp.

When all else fails - RTFM!

PC equipment gets old faster than audio. I still enjoy listening to my 7 year old Denon 3802 but my Pentium IV PC is long time gone.

Semi correct, sound cards generally don't have power amps on them, because they're not needed.
There are many soundcards that will output the correct voltage to drive a power amp properly.

Check out the HTPC section of this forum.

Most use HTPC for playing DVD/Blueray and streaming music/video to an AV pre-amp or receiver. This is even possible over HDMI now if you so desire.

The dream of also replacing your cablebox with a HTPC is frustrating at best because cable companies are backing away from CableCard support.

Probably designed for pro studio and such, and very expensive. But check with Sweetwater and I think their excellent pro sales staff will be able to help you as to what you can and can't do.

or not...acheiving a 1vp-p output level is not difficult or expensive.

M-Audio cards, which are pro level, are under $100.00

Creative x-fi is another one to consider, great specs and no pop/bang when your PC powers up/down!
