Flashunlock, I've spent way more $$$ than you. At this point, I have removed all of the cable chips from my system. I think they are just too overwelming on my cables. But, I do think a cable chip on the main breaker is a plus along with fuse chips on the individual breakers that go to my dedicated outlets.
At this point, I still have the Transformer and Cap(large, small)chips on my analog equipment. And of course the fuse chips on fuses.
