My NFB-11 setup for speakers: PC -> USB -> NFB-11 -> RCA preouts -> XLR inputs on a stereo Hypex amp. With this setup, I get a slight PC interference noise from the speakers that changes with varying loads on the computer - typical crappy PC sound. The moment I disconnect the USB cable the background gets dead quiet, so it's not a problem with the pre-amp or the amplifier itself. Also no noise over the headphones. Anyways, has anyone tried any USB isolators or perhaps disconnecting the ground or power leads on the USB cable? I thought that the USB implementation in the NFB-11 would ignore or isolate the power noise, but it doesn't seem so.
I can easily switch to using optical instead of USB, but just asking...
