Default CX-9GT.Noticeable hissing from loudspeakers.

Dear CX-9 2016-17 owners, whether somebody has noticed silent hissing in loudspeakers?
It is heard in all modes (radio, flash card, smartphone) always right after switch on, at the muffled situation, low volume or on a pause. I heard this in another CX-9 too.
It is probably such feature of premium BOSE sound system?

No hiss in mine.
The Bose system is far from premium. Bose should be embarrassed by the subwoofer that carries their name. The other parts are OK. I greatly improved my sub by sticking vinyl sound damping sheet (available from any audio equipment supply source) on all the flat surfaces of the sub and by putting some poly fill into the enclosure.
