Hi Panosher
Hard to say. I also had some problem recording the clicks and the audio file in the first post is a poor representation of what I actually heard. For me personally, these "clicks" were definitely audible and annoying. I think I can hear some of these clicks in your video as well, but since you are not sure of this yourself, we might be imagining things here. After all, only a few people were affected by this problem. If your iMac sound does not annoy you, I would not bother with a replacement.
