I do not even have a basic knowledge of electronics compared to 3D, but it seems to me he was suggesting a PSU upgrade. Not exactly digital electronics, is it? Besides that, isn't digital electronics either on or off, so it is really not as hard to implement as analogue audio circuitry which has a subjective outcome. (didn't some wise dude say something to that nature?)

Okay I'm sure you are all sick of me posting in this thread by now so I will stop!
