Thanks Newbee...Yes it is when I am at the speaker only that I can hear it, not from the listening position which is only about 8 or 9 feet away. I moved my ICs around a bit and there was no effect whatsoever, and they are shielded (97% according the manufacturer).
The sound is definately not that famous buzz noise which is usually associated with ground loops-which I have chased in the past. This is more of a hum, like a current flowing noise (IE transformer). Also, when you power this amp and the room is quiet you can hear it's initial draw. Kinda like a faint wuuuuunnnnnnhhhuuuuuunnnnhh noise. Bad description I know, but hopefully that describes it.
Outside of listening AT the speaker there is no noise, but where I am new to tube amps and experienced with SS this noise is new to me. If this is normal I can certainly live with it because the amp sound phenomenal. I just prefer to hear that delicious airy sound when my equipment is powered up.
