Protecting the signal lines is very important, IME. We see some of the nastiest damage in lightning strikes on the ground foils of audio equipment that does not have signal line protection. Having the grounds all tied together is probably the most important part, but having the ability to clamp voltages either way is also likely why we do not ever see damage on systems where every component is protected and every signal line goes through the surge suppressors. We use the Panamax equipment on virtually every system and I cannot recall ever having products damaged in any of our installs except those where cable or sat installers bypass the signal line progtection. I have repaired hundreds of components that were not part of our installations and did not have this kind of protection. I have come to believe based on this great disparity that proper protection, as descried by Panamax is very important. They have fine products, fine support, and a lifetime warranty. There are a few products that can be found with similar protection at a little lower price, but overall, they are a great value.
