iPod Video 5G 80 gig - White noise

I have an iPod Video 80 gig and I notice that their is always a background white noise (hiss). I start a music and press pause for this test.

When I close the volume I can hear a clip when the volume is close. As soon I increase the volume I hear a white noise (hiss) and it keep the same level until I get to the 3/4 of the volume then it's start to make the white noise louder and also I can here some clipping that is comming from the wheel until I get to max volume.

Clicker sound : OFF
EQ : OFF
Sound Check : OFF

The problem I got with this white noise is when I listen to calm music I always here the white noise (hiss) like I am listen to a tape cassette.

I was hearing this with my Sony MDR-EX70 but I just purchase the Ultimate Ears Super.Fi 5 Pro (white) and these headphone are so clear compared to my Sony that now I hear the white noise even more !

So I would like to know if this a poor SN ratio noise of the iPod built-in amplification or it is just my iPod and my friend iPod too ?

It would be interesting if a couple of people could try the test and see if they got the same background white noise.

- Start a music
- Pause
- Close the volume (should hear a click a the close position)
- Increase volume (should start to hear the white noise (hiss)
- Increase the volume to max and at about the 3/4 of the volume up to the max volume you should hear some clipping noise from the wheel sensors and the white noise should also increase in level up to the max volume.

If all iPod are doing this then Apple should redesign the amplification to increase the Signal to noise ratio better than what it is right now.

I would like to have some feedback on this from the people who gonna make this test.

Thanks
