A thought..
I have a Lynx Two-A soundcard in my DAW.
http://www.lynxstudio.com/lynxtwo.html
As good & remarkably silent for a card with in-the-box converters it is (the specs given by the manufacturer do seem to match up), I can hear the digital crap when I crank the monitors up and add some ~15dB of gain on an DA-AD loop.
I know, it's an extereme and I wouldn't worry about hiss and that kind of noise, but the sound created by mouse movement, HD operation and all is just too stupid to not care of.
Since the card is in the PCI bus with the solder side all exposed to the power supply, processor and all, I was wondering if it could be a worthwile experiment to shield the card from the solder side with some sort of a L-shaped mu-metal plate connected to chassis potential?
Or is this kind of crap typically already present at the circuit board (bleeding from digital ground)?
