The power lines that bring power to your home are generally not even insulated, they normally have corrosion protection at best but not insulation or shielding, this is one reason why you should never touch or come in contact with downed power lines, the lack of proper insulation. The power lines coming to your home are like antennas attracting noise and interference and other problems. The power lines as well as other electrical equipment in your home can create noise which may be constant or just momentary and poorly affect the audio and video of your system. A good power conditioner can help clean this noise up and shielded power cables in your system help to keep things clean further protecting your system.
True - but step-down-voltage transformer inductance from the power line filters almost all RF from the power line. The AC coming into your home has little RF. The equipment in your home (primarily motors) can generate brief noise at start up and shut down, but any audio electronic device has both transformer and capacitance filtering more than sufficient to cope.
I also need a bunch, but one need not buy a power conditioner to get extra outlets. There are a lot of very inexpensive power strips with the amperage capacity to daisy chain.
Although true, none of these monitoring "benefits" really changes the power. Even cheap power strips have surge protection. The devices being powered mostly all have their own isolation systems and trigger jacks. But since not all have trigger jacks, I guess that could be a unique benefit of a power conditioner.
And this brings up yet another argument against power conditioners in general. The customer knows not what they're buying. Even the same brand and model, as you point out, change over time without information about what has changed ever being available to the consumer. To buy a power conditioner is to buy "a pig in a poke."
Now all of that said, I have nothing against power conditioners - I just say caveat emptor (buyer beware). I have two Monster Power units in my system that I bought at significant discounts, and although I can't tell any difference by listening, it's fun to view the voltage and the current draw. And even with all the outlets on the two units combined, I still have to use "splitter-jacks" to get all my gear plugged in. Off the top of my head, I've got:
Cox cable box
Oppo disc player
2 mono power amps
2 to 4 subwoofers
Whatever device I'm reviewing at the time
for a grand total of 16 plugs to be serviced. I use one of the Monsters to handle all TV-related plugs, and the other for all audio ones.
