Audiophile Receptacle question

I've found that Hubbell hospital grade outlets are all that I need, but I have to confess that our local utility delivers an excellent product and my house wiring seems up to snuff.. Perhaps others with a questionable quality power source might benefit from some of the more "exotic" (and expensive) offerings that are available, but the hospital grade Hubbell's suit my system well.

Cheers,

About 2 or 3 years ago, I was inquisitive about outlets as well....tried many....returned many.   I kept top of the line carbon fiber Furutech...yes I know they are expensive.  Oyeida is also excellent, but in my house for my system, the Furutech wins.

You can use 12/3 or 14/3 Romex. The braided 4-wire is for 220v ranges & dryers. It’s braided because if it were solid you couldn’t pull it through studs and joists. Canceling EMI wasn’t really a consideration although it may work.

It’s not braided.

Some 3 wire + ground has a spiral its entire length. I have seen some that is flat.If using NM-B (Romex is a Trade Name) for best practices use 2 wire with ground.


If shielding is desired use 2 wire with insulated ground MC aluminum armor cable.
3 wire with ground (4 conductors) is not recommended be it Romex or MC cable.

I've  been upgrading all my equipment with Anticables Level 3 PC. They are decently priced and have improved the sound as advertised. Better dynamics, quieter background and better bass.
