it's the thrust bearing under the spring housing. if that went though you would know about it as it would rattle like a good one and have loads of play in the lever.

Re: Clutch noise - Curvy.
 
As a general guide you tend to notice clutch issues when you pull the lever in. This compresses the clutch springs and releases the pressure on the plates, allowing them to "rattle" and the inner and outer baskets to rotate in relation to each other. It also puts pressure on the release bearing. If you have a broken plate, or a knackered bearing, you will hear and feel it.

If on the other hand it is quiet when the clutch is pulled in, and the noise is when you release it then this tends to suggest gearbox as the inner basket is now turning and this is connected to the input shaft, and even with the gearbox in neutral all the various gears will be spinning on their shafts.

I'd want to hear this rattle/clunk before making that call. Have you changed the oil recently, was there anything nasty in there? My Hornet gearbox with over 50k hard miles on it makes quite a whirl in neutral but I wouldn't describe it as a rattle or knock.
I take it this noise is when stationary so we can eliminate chain etc...?

Clutch noise - Curvy.
 
I can hear the slight noise change, but my 2500 miles old sv does it and most cars do it. Sounds pretty normal to me.
