I posted this earlier, but as a novice poster, I think it was in the wrong place.
My question is: does one need both a dedicated surge protector and a dedicated AC filter? I'm using Chang Lightspeeds for filters. They are relatively expensive and provide little energy clamping (35-45 joules). On the other hand, surge protectors providing up to 3000 joules energy clamping can be had for relatively modest cash outlays. If one needs both, does a proximal (nearer the AC wall outlet) surge protector degrade the performance of a distal line filter?
Thanks, John
