I'm some problems with static. If the source is silent and I touch the chassis of the Bifrost or the chasis of the Valhalla - I get static through the headphones. I noticed this first when my headphone cables were draped over my computer monitor. I thought the monitor was the source of the interference. I moved the head phone cables out of the way and touched the amp - static.
So do I have a ground problem?
My first Lyr had some static but the this one that I have now is dead quiet.
