different sounds from cluth

[Luigi]

hi guys.
i have an ibiza mk4 1.4 16v 100 bg at 110k since 2004. Last month, a sound like "tirrrrrrrrrrrrrrrrrr" starts to come from clutch.
I had changed the clutch pressure plate with new one at service. They had also changed clutch bearing. But the sound continues.

It' s coming when i'm accelarating especcially at 1st and 2nd gear and it's coming more when engine rpm is going up. It's very easy to hear between 2500-3500 rpm
When i depressed clutch pedal, it continues but it is very hard to hear
When i put gear in neutral, there is no sound

Sound is not coming from clutch bearing, because they had changed with the clutch. What can else it could be?

The first thing I thought of was the clutch bearing, but as that has been changed it seems unlikley - unless its a faulty part? The only other thing I can think of is that the clutch just hasnt had time to wear in yet.

it took roughly 10k miles for my std clutch to wear in
