Electrical Power Outlet advice

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!

You are always better off to connect ALL components to a SINGLE but adequately rated outlet to eliminate ground loops.  The star connection of this configuration minimizes the ground loop possibility, which may cause humming & buzzing in some situations.

My  electrician is a Audiophile ,I followed his lead.

i hav3 Copper gold outlets ,

awg 10 copper wiring in a 30 amp  breaker , and the 4 wire 

dual ground 1 is common the other a insulated is located ground on its own strip in the breaker box ,then grounded to a 4 ft Copper Rod  and the Breaker is a Siemens from Germany solid Silver which was $60 , the stock copper breakers are $12.

night and night better sound ,very black back ground.

This is a solid performer that’s reasonably priced:

Audio Advisor sells it. It is well made & grips better than any other outlet I’ve owned

How far you go will depend on your audio system upgrade aspirations. If possible. it would be good to get the grounding sorted while you can too, but be prepared for revealing sound reproduction issues you have not experienced before.

If you want to go the full distance, install a dedicated grounding system with copper tape and rods drilled and grouted into bedrock, outside your room. Place Bentonite clay beneath the mat and keep damp to maintain low resitivity. For peace of mind, get your electrician to do a resistivity test. The lower the Ohm number, the better it is conducting to ground. Appreciate that this may not be physically and financially justified now, but you may wish you had done it later (???)
