The all in one USB solutions will almost definately be the easiest (Read STILL REALLY STINKIN' HARD) and cheapest to implement ... if you can avoid PCI i suggest you do so ... for starters there are about 10 different versions of the PCI spec.

Well, I'm up to a challenge, after all I have contacts with people who build soundcards for a living (ever hear of mediatrix?), so I could always get help. I agree that the micronas chip would be the way to go, but I can't find a place to purchase micronas chips in single units. I've been looking for a place to purchase a micronas MAS3507D and a DAC3550A without any luck for a little while now...

Also, I was looking at the micronas UAC355xB, haven't looked at the UAC3552A yet...

Thats the one i was looking at, too...I cut and pasted the wrong number.

I'll probably just buy a Stereo-Link or something from Roland, anyway, but thinking about building my own is fun.

Default source

There's links to several sources for the MP3 chips, they'll probably have the USB one, too.

Well, this idea is something I'd like to eventually do, I'll probably talk to a professional on it this summer. But for now if I wanted better soundcard sound I was thinking of just modding my current soundcard. For the situation it's being used the soundcard has to be a SB16. But I noticed that it used a TDA1517P which is a 6W per channel 2-channel class-b amplifier. Now, I don't want my sound to be amplified since it's going to my pre-amp right after the soundcard. This amplifier is for non-active computer speakers, correct? So removing it and bypassing it should work out fine, correct again?

Some cards I've seen have a jumper to bypass the amp and give a line-level output.

also you'll find that the quality of the sound output from a sound card is inherently limited by high frequency noise present inside a computer.... the answer? you use the sound card to output a balanced digital signal then you do the processing outside the computer case.

Indeed. There are a few other options Creative Labs have come up with you guys might be interested:

- SB Extigy - external USB sound, nice looking and presumably as good quality as the Audigy.

- SB Live/Audigy S/PDIF coaxial output. Platinum eX version has the Audigy Drive in a format that can be connected externally via 2m cable. You can also buy a 3rd party adapter that will provide optical output for as little as $20

- SB Live Drive / Audigy Drive Optical output. They're expensive for what they are, though.

- Wrapping your sound card in insulated metal foil. It works fairly well, I've done it.

The soundcard is in a set-top box so I can't use any fancy cards with weird boxes and such. I'll probably just wrap it in foil. Should be good enough...

JoeBob, I just had an idea. Check this out:

If you are really interested in a PCI based solution, there is an alternative that can get you there without all of the pain and suffering of a custom PCI layout. See if you can get a hold of a PCI prototyping board. I can't think of any sources offhand that I know has them, but some of the programmable vendors like Altera and Xilinx may be a good start. Or, you could just do a search on Google for "pci prototyping board" and see what you get.

Ideally, you can find one with a dedicated PCI to xxx interface chip already there, to which you can attach the audio controller of your choice. You will have to figure out a way to add the DACs, since I think it would be quite hard to find a board with ones already designed in.

I'd be interested to see what you can find.
