Electrical Power Outlet advice

Interesting article thanks Ieales I also needed to post a correction ,There is a typo in my post the 1.3 stated amperage draw of my system is actually 4.3 amps , which is close to exactly what the stated wattage of the pieces added up then converted to amperage should be. 

I have no first hand experience with this new Leviton receptacle, but I saw it awhile back ,Leviton GFTR2-IGO ,its a polycarbonate (not nylon) 20 amp isolated ground ,tamper resistant GFCI, I personally don’t believe in the need for GFI,s indoors but this plug checks all your boxes, best!

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

+1 Carlsbad, you dont need two but we as a general rule would always run two as the labor is essentially going to be the same with a little extra for wire and the recepto.You can use it for non audio and you have back up circuit, you never can tell what might happen or what you might add to the room. Whatever you do dont add a 30 amp circuit with giant oversized wire, all these components are designed to be run on 20 amp or even 15 amp household AC. After I completed my new set up with its 20 amp home run I fired everything up and put my amp clamp on the cable from the wall to the Torus power conditioner. At idle with everything burning its 1.3 amps  and at ear splitting volumes it’s maybe double that in short peaks.amp Breaker’s normally will trip at about 80% of the stated value, Your never going to exceed that unless somethings wrong in which case you need that breaker. Best!
