Hi... Can anyone share any knowledge about whether or not it is wise, needed, essential, silly (?) to install a surge protector for an A/V system (HR10-250, Pioneer amplifier, Panasonic plasma tv) that also has sat(in) and sat(out) surge protected feed throughs?? Are those coax surge protectors hype or something one should really hook up??? And is there truth to what I've read a couple places about some of even the more expensive surge protectors not being able to pass hdtv signals??? Currently I have an old and inexpensive surge protector on the power outlet by my A/V system and I am trying to decide what is the best thing to buy to correctly protect the system... I just got my D* system up and running a week ago... Any input would be much appreciated... thanks...
