NAD 326 headphone noise issue ?

Hi!

I have a problem with the headphone!
When i turn on the amplifier (Nad 326bee) using headphone, there is a noise (like a "bumm"), and when i turn it off, after about 2 secounds there is another noise like a siren, then a clipping sound.
It is normal or an issue (i heard this on 2 amplifier with 3 different headphones)?

Thank you very much!

Is this problem for the headphones?

Some integrated amps doesn't have a well designed headphone output section, that's probably the cause of your issue.

Which headphone models are you using?

I use Senn EH350, but i tried an Onkyo DP-400.
The NAD support center wrote that is not normal, but i found other users who has this problem too (on the speakers everythings right). The 2 new amp (which i tried) serial number very different and were different dealers.

Thank a lot!
