Do You Really Need a Discrete Sound Card?
crookedvulture writes "Integrated audio has become a common freebie on motherboards, causing many to question whether there's any need to have a sound card. Tech Report took a closer look at the issue by testing the latest integrated Realtek codec against a couple of sound cards: Asus' $30 Xonar DG and its considerably more expensive $280 Xense cousin. Everything from gaming performance to signal quality is explored, and it's the blind listening tests that prove most revealing. The integrated solution is obviously flawed, and in a bit of a surprise, the cheaper Xonar is the one most preferred. Discrete sound cards certainly have their benefits, and you don't need to spend a lot to get something that sounds a lot better than the average motherboard."
In my experience, the only time it's worth having a discrete sound card is if you have a kick-ass set of headphones (or speaker setup). For the average $100 set of headphones/$400 speaker setup? Totally unecessary. Now, it's worth it if you want "surround" virtualization with headphones, but otherwise, again, totally unecessary.
Of course, if you truly care about sound quality, you'll just use a digital output (either through USB or Optical) and buy a nice external DAC, thereby completely bypassing any potential electrical interference generated from a sound card.
Note: I run an ATH-AD700 off my built-in sound card and I think it sounds great, so no accusations of audiodouchebaggery on my part, please.

My motherboard has optical SPDIF in and I'd never use a DAC in the PC environment, it's just too noisy.
I used to think the same thing too. Amazingly enough, you can engineer your way around the noise and create a very good sound card, at least from my informal experience with a handful of different cards. That said, most motherboard solutions (including laptop versions, unfortunately) are nearly worthless because of the price optimization pressure.
Some years ago, I had an undergraduate student design an audio I/O card for a research computer we were developing. She did a remarkably good job. Despite being buried in the middle of an environment with a fair bit of electrical noise, the card produced quite good sound that was essentially as quiet as it would be as if it were in a separate enclosure. She had proper power supply and ground isolation, local re-regulation, and ran all signal traces on internal layers with ground/power planes on the external faces of the PCB. Worked great.

I've been in the industry for about 25 years. And I can tell. I have a media center set up with about 15 speakers in all. I definitely can tell. I don't disagree with you that sound quality and features are better with an add-in card. I just don't agree that sound quality is that bad with on-board audio.

I prefer language to be understandable in both its written and spoken forms.
It is, but that's why we have separate dialects for speech and for writing. There's no need to compensate for the weaknesses of one in the dialect used for the other.
