slight noise concern with lamm amplifier?

Hey,

I am not sure if I am just a tad concerned about nothing but I notice that if I have my new lamm 2.2 amp on with all the other equipment on as well but no music playing that if I put my ear next to the speaker I hear a slight amount of snowy sound. I cannot hear it if I step away even a foot or two from the speaker. It certainly not a hum or buzz sound. I am not sure if this is normal (the volume is not on). The amp is connected to a 20a line. I do not remember whether I checked this on my last amp or not. If I have the preamp on but not the amp there is no such sound.

I know that the lamm 2.2 has a ground connection and now I am wondering whether regardless if these issues are connected I should use the ground connection somehow.

any thoughts?

Thanks as always

Gs5556 is correct.
I have that with my Lamm M2.1s, and my friends have it with their Lamms as well.
(I have had that with all my amplifiers actually.)

Okay, I am curious though:
What amp(s) were you running before that you did not have this noise?

PS How do you like the Lamms so far?
