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!!!
