Honestly I have not heard it so I will refrain from comment about it, logic, however, seems to be that anything getting power from your computer, particularly inside of your computer, is going to sound worse. To further that, it is not only feeding power to the dac, but the amp topology on the same card. Now, I dont want to talk about the caps, resistors, transistors, etc. but I think the power arguement is a strong enough case against having an internal soundcard regardless of the make and technology. I do not believe from what I read that it is charging a battery from the pc power and using the power from that, so that means its directly exposed to your pc power supply, which is bad. I am not talking about shielding, just the fact that it is using the pci slot for its power source.
