audiophile grade sub panel and breakers?

He’s also installing a new 8’ ground rod specifically for the sub panel. He mentioned he would use a insulated wire for that. Which would go from the ground rod to the sub panel and then (I think) to each 20amp outlet.

You probably misunderstood your electrician because what you describe doesn't satisfy NEC. You need to have all the grounds bonded together at the main panel only where they connect to the utility's ground and your safety ground rods. Having a separate ground rod for a subpanel is hazardous because a fault won't trip the breaker. All grounds and neutrals tie together at the main panel and at the main panel only.

I I probably did misunderstand him. 🤷🏻‍♂️
He’s actually very qualified and knows a lot about getting the best AC to my room. 
He mentioned another product that said would clean up the entire house but I’m not sure what it was just yet but it wasn’t the Environmental Potentials product. 
I’m waiting to here back about that. 

Also, I was looking at the Square D panels mentioned here but this is an older thread I was told that Siemens PL series was a good one as of now. 

Thank you Jim. It is obviously unwise to argue with Mr Ott. The only important issue in your house's electrical system, assuming your electrician was good at his job is that each circuit can handle the load it will be subjected to. Otherwise this is all nonsense and a great waste of time and money. Buy more music or a more powerful amp or better speakers. Chasing minuscule or imagined improvements is a fool's game.
