I got a Joule pre-amp some time ago and noticed a very slight hiss and hum in one channel of my system after I installed it. I couldn't hear it unless I put my ear right up next to the speaker. I called Judd Barber and asked him what to do. He said, "Don't stick your ear in the speaker."
I eventually concluded that this was reasonable and appropriate advice, and didn't do it again.
