Electrical Power Outlet advice

Buy American. The stuff from China is utter garbage.

You are better off to have an overcurrent circuit [20A] and multiple outlets closely connected that spread outlets on multiple circuits. That being said, a 12ga / 20A circuit at full current drops a tiny fraction of a dB in power capability. Most audiophools have not a clue about HiFi A/C power requirements. See ieLogical CableSnakeOil A/C Wiring. Music has next to  Z E R O  temporal synchronicity with mains Hz. Current peaks are supplied by the amplifier power supply capacitors.

Depending where you live a surge suppressor is a probably waste. In all probability, it will fail when needed most. Good ones C O $$$$$$$$$$$ T !!

DO NOT additional grounds rods. It can reduce the effectivity of what little protection against a lightning strike they provide. It will cost B I G $$$$$$$$$ to engineer and install something more effective than NEC requirements.

These are a lot of different paths to take. It seems there’s a higher consensus for the GFCI circuit breaker, eliminating the need for multiple individual GFCI outlets. I need at least 3 new outlets. One for Primare power amp, and 2 for Synergistic research FEQx4 which needs 2 plugs.

@cakyol when you say "connect ALL components to a SINGLE but adequately rated outlet" do you mean something like this?

@mewsickbuff 

Yes, pretty much.

Op  you can protect up to 5 regular oullets behind a single GFI.
