How about whole house surge/lightning protection installed at service panel by the utility company?

Most dedicated lines of which I am aware originate in the service panel for the whole house. You could have your electric company drop another service line from the transformer and have a second panel but that would cost a bit and I'm dubious that the power would be any cleaner than you would get from the main panel. My lines originate in the main service panel and are dead quiet. I suppose it could be a problem if your other power usage taxed the capacity of the main panel, not a common problem I suspect.
Ken I can share my personal experiences with much of what you described; my results have been very successful, cost effective & highly sonically satisfying. I won't explain the full story here (although you may email me for further details).
Install one or more dedicated 30 amp circuits of #10awg THHN solid copper. A special twist-shielding technique is advised for best results (request further details if desired). Terminate with a high grade AC outlet; the "Porter Ports" you've seen advertised here are but one example of a quality outlet (I use the pricey-but-worth-it Wattgate 381).
Keep your Changs. I have the 2500 for source components & the 9900 for high current components. Run your high-quality upgrade AC cords from the Chang outputs, thus retaining the Changs filtration & transient-protection. This works just fine with upgrade cords. My cords vary from $200 to $2000 & all work well via the Changs' outputs.
[Lately I've been experimanting with an Audio Magic Matrix line conditioner / transient protector. Different sonic signature but has similar benefits as the Changs.]
Because we live in high-lightning areas (I'm in central Illinois farmland) we need an additional layer of protection; a whole-house lightning arrestor installed at the service panel in parallel with the incoming line. Just like inside of the (Chang's / MOV's) a whole-house unit is wired in parallel so there's no effect on your sound & no current-flow constriction whatsoever. During a line-transient event, the whole house arrestor shunts the majority of the voltage surge while the secondary unit(Chang) attenuates the remainder of the spike.
I use a whole house gas-tube discharge arrestor made by Joslyn Electronic Systems. Joslyn's are a superior product indeed, but if I'm at home when the storms come rolling in I still power down the rig & UNPLUG everything!!!
Newbee and others, be careful. Even if you trip the breaker at the panel, you are not protected from lightning. Spikes and strikes often travel through the ground wire. If you want to be sure, unplug all of those components. When I see a mean storm heading my way, thats what I do. I also have a whole house surge device, which is installed at the panel that actualy draws the spike away from the panel in the event of a lightning strike or power company surge (which does happen). The devivce is sacrificial, a big spike will kill the unit. an example...
What happened to lightening rods? My son had them in Michigan, but I have never seen them on a modern house. Unlike surge protection, I suspect they would not screw up your sound.
As I have said before my house was hit by lightening with my entire stereo system on. The lightening hit 5 feet away from my system. Everything was plugged into a Sound Application filter. My garage door opener, my intercom system, and my answer phone were all ruined by the strike. Nothing was harmed at all in my stereo.
Guys, anyone with any advice on brands for whole house protection?
Several have been mentioned to me, but al only have anecdotal references. I could use Florida Power, for an added fee. What is best? Is one more cost effective than the other options? I personally am not worried about small differences in price, I want the best protection I can get, to prevent me buying another 7 amps!
What do you guys think??? Gals too.....
