Low amount of buzz okay?

Hi all.
So compenents, arcam a65+ integrated used as preamp, odyssey strattos extreme SE +++, PSB imagine T.

The buzz (which does not sound to me anywhere close to 60hz, more higher frequency), is only listenable if I place my ears 6 inches or closer to speaker.

Is this that "big" of a deal? I mean, even if I try everything I can to isolate the noise, change wiring, etc...
Is this going to have any effect on my listening? Or quality of output?

I guess the ultimate question is: Is this amount of noise "normal"?

thanks much!
