I just bought a Portal Audio Panache today and hooked everything up. What I first noticed upon power up was a very loud buzz. It is so loud that I can hear it from anywhere in my room. So I checked all connections, changed power cords, used a cheater plug, changed socket, unplugged all sources and nothing will get rid of this BUZZ. It is the same volume no matter what the volume is set to, same on every input and is the same through the headphone out. What can this be!? Please has anyone had this problem before? I have had three amps before this in the same room on the same socket and never had this problem. I have even gone through the house and turned off all the lights.

I am so upset about this.
