The point on his sound card is actually well placed and it would probably be a good start if AMD listed exactly which card he's using, on which OS, with which drivers and how he has it connected to his receiver.

There's even a company that makes a sound card for your computer that uses a vaccuum tube. I just read about it recently, so I don't know any specfics, but i'm sure it's pricey.
It's not a soundcard. It's actually the AOpen AX4B 533 motherboard that uses a tube amp for the onboard sound, a ridiculous suggestion by AOpen. Tubes are very susceptible to EM disturbance and the inside of a computer with a massive switch mode power supply is about as EM heavy an environment as you can find. What's more, tube amps require high temperatures to opperate and I sure as hell don't want that kind of heat in my carefully cooled system.
