Wow! I just turned on my keyboard amp (I've been using the headphones lately- see below) and the usual low level of line noise is hideously dirty! There are clicks, pops and static like I've never heard before. I have two new neighbors in this house (split into four apartments) whom must have electrical components unlike the previous neighbors or they're using outlets the others didn't.
The sound of my keyboard is clean in Sonar through my PC, seems clean in my stereo when routed through my PC soundcard and is clear as a bell in a set of computer speakers I'm using for cheap keyboard monitors (plugged into the keyboard).
But the keyboard amp is messy, whether it's the keyboard or a POD (Line6) routed directly to it.
Any suggestions?

Try different outlets in your house. Try a different house. Wiggle your cords and connections. Try it late at night , or when all the other tenants are gone. You can buy line filters at Radio Shack that aren't too expensive.

Basic troubleshooting principles show that, if the problem is universal to all devices, then the problem may be power-related. If other devices work well and just the one device is not working, then the power is probably OK, it's just a flaky failure in that one device. Perhaps a loose connection or faulty component someplace, or even just the headphone cord or the jack on the amp. Correcting a power problem that doesn't show up on any other device isn't logical. You need to isolate the problem - first try new headphones, and then try a new headphone amp (which I would say is the problem here).

If, by AC power, you refer to your wall outlet, then the only solution I know is to buy a battery-backup device (about $60 up and down from there) WITH >>> AVR <<< as part of its package and/or model discription. I bought one even though I am inside an apartment LAN that has its own protections for me and I survived a direct hit by lightening on the LAN while others lost their PCs outright. ANd that is the ultimate test of dirty AC. In fact, I kept right on connected to the Web even while the lights went out, flickered several times and then returned. If you are at home and not in a LAN, you are at serious risk at all times (One of the dirty little secrets your power company doesn't talk about.)
If my initial assumption is wrong about your problem, then I don't know a solution for you.

A good quality battery backup / UPS (i.e. for a computer) will clean it up a bit. They're a bit pricey though, but cheaper than a heavy duty voltage filter.
And fixing the voltage is cleaner than trying to filter out the noise after.
