Cleaning power with tweaks.

Try a daisy chain of Richard Gray power cubes. Add them as you can.
Seems to me you’re in the dome of noise. Try anything that will lower the noise. It all does something but you may not know how much because a worse sounding connection is covering up. So when you solve the mother problem, the little ones will follow along.
I like to remind myself that my end goal in this is to hear the music as clearly as possible via whatever equipment I have. Science shows us that almost any gear will transmit a signal to a speaker with incredible accuracy. What happens along the way is simply added noise. You really need a dedicated line for at least part of your system.

Clean all wall outlets in the house, including those used for appliances, lamps, TV, fridge, etc.

It is my experience after my very simple experiments....

All gear that are only good could be suddenly amazingly good if someone gives a try to controls the electrical, mechanical, and acoustical embeddings.....

@deanshias,

First, do you have your Hydra 6 supported and decoupled like a standard component? Since you already use Shunyata, look for a used Hydra 8 or better. Daisy chain the 6 into that. I’ve done it and recommend it.

slaw: Not sure what you mean by supported and decoupled.  It goes into an audioquest nrg edison outlet (which made a significant change). And the other PowerCenter conditioner goes into the same outlet. And its ok to plug  a power conditioner into another conditioner? 

geoffkait: how do you clean wall outlets?
