IMO, the first step would be to install dedicated AC lines from your circuit panel, if possible. This would isolate your audio from other circuits and appliances that add noise throughout your AC mains.
Regarding power conditioning, if you have stable voltage coming into your house, you probably don’t need a regenerator. If you have had good results with the Richard Gray 400, then stay with a passive PC.
I’m not familiar with the Ayre PC, but it claims to be non-current limiting which would be a benefit to your amp’s performance. I believe the Gray passive PC’s do limit current, as many passives do, and your amp would be better served by going directly into the wall.
Sorry I can’t be more help, I just tried to point out the pros and cons of reducing the noise floor in your situation.
You’re already using aftermarket PCs, are you asking if you should upgrade? Changing one cable is not going to be all that noticable except for maybe a slightly different sonic signature. It seems like the priority is to add more receptacles while lowering the noise floor.
