Very faint hiss from tweeter

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

FWIW, I have an A23+ with an LTA tube preamp, a Schiit Bitfrost 2/64, and a Schiit Kara. The LTA runs through the Kara in passive mode, or I use the Kara for SS. A basic Furman surge protector and no other exotic cables. 

When I put my ear up to my tweeter I hear nothing. When I introduced a Schiit Lokius to my system, I heard hiss when I listened to the tweeter. When I removed it, the hiss disappeared.
