I just put a new system together and noticed that when no music is playing, if I put my ear very close to the tweeter on either speaker, there is a very faint hiss sound.  Is this indicative of a problem?  Its not audible unless my ear is very close to the tweeter, but I wonder if its polluting amplified sound when I play music.  Should a system be stone cold silent when powered on with no music playing?

Heres my stack:
Focal Aria 936
Parasound A23+
Schiit Freya+
Bluesound Node X
