Any one try the new Synergistic Research BLUE UEF Duplex receptacle?

Jea, Your point is fairly taken.  However, there is some "science" around power cords and interconnects, to name just two elements.  Power cords may be heavy enough in gauge to transfer the current needed by the component, or not.  They may be shielded, or not.  They may be configured so as to be capacitative and/or inductive to one degree or another, and there are some known ways in which these properties could affect sound.  Likewise for ICs, if you delete the bit about current carrying.  Plus, as you suggest, I rely upon personal experience and the reports of a few trusted sources as regards these and some other ancillaries. But in the case of the SR AC outlets, we have.... what?  What is there about a black AC outlet that would make it sound different from a blue or a red one?  (Obviously, there could be differences that I don't know about, but why doesn't SR tell me about them, is my point?)

Off subject.
Has any tried the Audioquest NRG Edison Duplex Wall Outlet?

It is not just a rebranded mass produced outlet.

Internal contacts

Beryllium-Copper Base Metal Provides superior spring tension and long-lasting, low-impedance AC power connections. Typical materials such as brass, or even high-purity copper aided by spring and wedge devices, simply cannot equal the unparalleled retention strength of high-mass beryllium-copper.

Beryllium copper (BeCu), also known as copper beryllium (CuBe), beryllium bronze and spring copper, is a copper alloy with 0.5—3% beryllium and sometimes other elements. Beryllium copper combines high strength with non-magnetic and non-sparking qualities. It has excellent metalworking, forming and machining properties. It has many specialized applications in tools for hazardous environments, musical instruments, precision measurement devices, bullets, and aerospace. Beryllium alloys present a toxic inhalation hazard during manufacture.

My son gave me one recently for my birthday. At present, for about a week now, I have it feeding the refrigerator. No complaints so far from the frig.


Here’s a link of a seller that shows a close up look of the outlet.

Interesting...thanks for the information jea48 :-)

@jea48

The Audioquest duplex that you referenced looks to have similar construction to the Cardas 4181US duplex with features like Beryllium Copper contacts, plated with Rhodium over Silver. The Audioquest duplex is only plated with silver but it includes a wall plate.
