Dear @infection : No, certainly is not normal that hiss/hum you are experienced with your PS ( especially at that " moderated " SPLs. ) that even has a lower noise level than the top of the line Reference in Whest catalog. You unit must be totally silent by design.
So exist a problem in your unit that it's out of specs or contaminated from other audio system link. The hum could be a ground loop or maybe the orientation of the IC phono cable.
Anyway, exist a trouble down there.
Regards and enjoy the MUSIC NOT DISTORTIONS,
