Improving on dedicated outlets to my audio room?


I have two dedicated 20amp outlets (using 10/3 wire) going to my audio room. 
I also have Audioquest’s NRG Edison 20amp outlets. I’ve got a Furman SPR20i and a Furman Elite PF20i. 
System sounds great but is there anything else I can have done to improve on it? 
I’ve been told by my electrician that will be coming by tomorrow to look at some things that my electric company has some of the dirtiest electric even at the plant. 
So I’m looking to see what you’ve done to improve everything.

I’m sure my Furman’s are taking care of anything at the equipment end. They are some high quality pieces.

😂 How much time (and money) do you have?

Nice!

Is there anything you’ve done to to the system before the electric gets to your room? Sub panel? Dedicated outlets? Etc?
Before it gets to the panel.
