Naim Mu-so Qb 2 a noise was heard, a slight hiss

Good day to all!
Naim Mu-so Qb 2 Generation Firmware 4.3.2 (6482)
I accidentally noticed that at a distance of 10-15 centimeters from the Naim Mu-so Qb 2 a noise was heard, a slight hiss. At a greater distance and when playing music at different volumes, there is no hissing noise!
Is this the case for everyone or is it just me?

I checked it with different types of connections to the electrical network and different sources of electricity.

Am I wondering if everyone has this minor noise or hissing or is it just me?

I have a QB Mk1.

It also hisses as you’ve described.

I’m interested in - Naim Mu-so Qb 2 Generation!

Please inform!!!

The hissing is quiet, not strong

I have two Muso’s 2nd Gen and a Muso QB 2nd gen. They all hiss.

Thanks for your reply!
Then I won’t contact technical support. And I will not return my speaker system.
I thought that I had got a marriage.
