I just noticed what my ceiling fan is doing to my amp. My wife was pulling the cord to change the speed of the fan while I was under the phones. It popped so bad it finally shut off.
I had no idea it was that bad. I am searching for line conditioners and trying to get up to speed. Alot of them seem to not have the rfi amd mfi filters I need. Any quick ideas for me? Do I need a seperate filter just for the rfi?

Sounds like the protection circuit cut in. Was your amp overheated?

RF doesn't always get into your system through the power cord. The coils in the motors kick off the RF, and it can be picked up by interconnects, the chassis, etc. Still, it doesn't hurt to have an EMI filtered inlet; I use EMI filtered IEC jacks on my gear. You may or may not be able to retrofit one to your rig. If not, you could always build one into an external box that then goes to your amp. It's pretty cheap, I get the jacks for about $1.30 at the local electronics store. You might also want to use some shielded cables for your interconnects. Don't break the bank. If you can't find cheap ones, you can always buy shielded cable and put RCA jacks on it.

If your ceiling has a variable speed control vs. just an off/on switch on the wall, this uses a transformer that will add all kinds of noise to the line. Can you put your amp on a different circuit or are all the outlets in the room on the same circuit? Your are going to have a tough time cleaning up the noise. A dedicated line if possible is always the best first step for any audio system before going to power conditioners. Get as much off the junk in your house of the lines that run to your system.
It also sounds like from your description that the circuit may have too much stuff on it to begin with. What else do you have on it?
Most EMI filter IEC are junk in my opinion, not form a filtering aspect but from a sound quality aspect. If I need filtration on the IEC I usually bypass using one of those and put a high voltage .47uf cap in parallel.

No amount of RF or line noise is going to make an amp turn off. He's got some sort of overheating problem or failing power transformer.

This is an apartment and the fan has a variable speed control on a chain. I will try different outputs, but it sounds like it won't matter if it's rfi being broadcast. I was thinking the noise was traveling through the line.
I didn't check to see if the amp was overheating or not. I think I may try to replace the fan. I will check out some good shielded cables and check into rigging up some kind of EMI filtered inlet. The amp is a corda aria and I am pretty sure it is in working order.
Thanks all.

You're fixing the wrong thing. The problem isn't the line noise... It's what caused your amp to shut down. If your amp is enclosed in some sort of cabinet, take it out or put a fan on it to cool it. If you don't figure out what caused the shutdown, your amp may shut down for good one of these days.
