I know this has been discussed before (see http://www.hometheaterforum.com/htfo...threadid=13486), but I thought I'd revisit it as now that I've upgraded my 3 front speakers (to nOrh Mini 9.0), and my amp (Sherbourn 5/1500A) I am now experiencing this problem. Did anything ever come of this? Is it definitely the source material? It doesn't seem to happen with all titles, but for instance the other night I was watching 'Kiss Of The Dragon' and it was happening a lot, whenever the characters shouted really loud, I hear the very subtle crackle. I've tried mixing and matching the speakers and it's still a problem. Is there a way to confirm that it's not the amp? The crackle is very subtle, and only happens when I have the volume at or above about 5 dB below reference, but it is just really annoying because I'm thinking about it the whole time.
