I noticed with the PLYR1 that when I navigate the PS3 XMB...the initial first UI "click" noise when navigating the menus is very soft almost inaudible (couldn't hear it until I bumped up the volume). I also occasionally hear a brief popping/clicking noise when going from silence to audio. I can consistently reproduce this in DVDs by jumping between the different pages for scene selection. Bringing it up because it doesn't seem to happen on the XP400s or maybe its just not as audible.
Is this like due to changing of source or audio format or something like what people complain about with some audio receivers? A normal occurrence on some headphones?
