that's a tough one.
You need to make sure your outlet is supremely good and your cord is rock solidly connected to the outlet (PS Audio Soloist, Porter Ports, or the like). Then I would get a reasonably priced shielded cable from Signal Cable for the full length you need and run that to a PS Audio Duet (4 ports). I would not plug anything into the other port at the source, and find out what else is on that circuit, and take those off if at all possible.
from the PS Audio Duet I would plug in power amps directly, and I would sell the Hydra and buy an APC S-20. It is great conditioning, and back up. That means you never run out of juice, even when the power goes off you can power things down one at a time. In fact, looking at your system, you could just go a PS Audio Soloist at the wall, to the Signal Cable power cord, to the APC s-20 and plug everything into that. I think you would see a huge improvment.
I have not used them, but I have buddies who live in apartments and swear by the PS Audio Noise Harvesters to help knock out noise in situations with multiple wiring.
Good luck
