Adam,
While I, like Bob use Chang PC's (I have the 9600, HT 1000, and 9900 amp models in my two systems now), I don't know if that will solve your problem. Yes, for many of the reasons listed above, it may help, but I don't think your components are the main trouble. I have had this problem with B&W's speakers (I had the original 802's) and have always heard what to my ears is an over abundance of sibilance from their speakers ever since....
I live in the lightning capital of the world, and as such always use power conditioning... and hell even have UPC's on my Replay and cable box in the one system... but I suspect you will find your real problem is the B&W sound.
