Signature™ Socket Double with Ground Terminal
5 out of 5
Russ Andrews Signature Socket™ with Earth Terminal
We’re big fans of the Audio Quality Mains Plugs we now fit to our Evolution PowerKords and SuperKords, and the top-of-the-range rhodium-plated versions are particularly fine performers. Knowing how good the rhodium-plated mains plugs (and indeed the rhodium plated Wattage IEC plugs) sound, we turned our attention to the 13A wall socket.
We’ve worked with a manufacturer to develop one and we can confidently say that our new Signature Socket is the best sounding UK socket we’ve auditioned. The existing UltraSockets are good, but the Signature Socket is a significant step up and is the very best 13A socket in our range.
Rhodium Plating
The socket contacts themselves are made with phosphor bronze copper alloy; their high spring rate ensures a tight fit on all the plugs we’ve tested them with. All of the contact surfaces, along with the screws that hold the conductors in place, are plated with rhodium plating of the same quality as that used on our Audio Quality mains plugs.Rhodium is an exceptionally hard and tough metal, making it perfect for environments where 'fit and forget' performance is crucial. The conductivity of rhodium remains constant over its lifetime, unlike other conductors that can deteriorate due to oxidation.
Process-Q
As well as benefiting from a high performance plating, each Signature Socket is treated with exactly the same full Process-Q treatment that we can apply to our cables.
Unswitched sockets
As with all of the sockets we offer, the Signature Socket is unswitched – our tests have shown that switched sockets sound worse than switchless ones because the switch adds an unnecessary connection that raises mains impedance.Ground Terminal
For those who are not using an external Ground Rod to connect to their RF Router MKII or SuperRouter, the external earth terminal on the front of this socket allows an alternative connection to Ground, via the household mains earth. It also allows those who are using a Ground Rod to connect it to their ring main earth, via an RF Router, and thereby ground RF noise on the mains.

"Unbelieveable Sound Per Pound Upgrade..."
I have the Signature socket with earth and it provides even more amazing musicality. What is musicality? Well, the Santana track Soul Sacrifice has a guitar note stretched out towards the end at around 6.20...I never considered it before, but with the Signature socket it is a cry filled with fury and it transfixes me, I am in awe and then bang...the track ends and I'm left speechless. I've been listening to this track for donkey's years...I have 600 plus cds, what else lies in store? So there you have it. Buy it.

"Outstanding!"
Like many audiophiles my system is now subject to the occasional “ tweak”. Earlier in the year I invested in Zapperators to good effect. In the last ten days of 2022 it was the Signature Socket. Initially it was for the double socket which feeds my mains block and the main components of my Meridian system. The result was really quite profound - with a much lower noise level together with delicious detail and openness. My TV sound was far more engaging. Overall I was delighted- which made me call John just after Christmas to buy a second - this time it was used to feed my LG Oled TV and my Oppo 4K Blu-Ray Player. The TV picture is far clearer and TV sound again had improved separation and detail. I had advised my wife not to buy me a present this year- an intention that soon dissolved thanks to the Three Musketeers : Peter, John and Simon!If you already use Rhodium coated plugs then the Russ Andrews Signature Socket is a must…..and another “tweak “ to tick off!

"Raises The Performance Of The Whole System"
Like all the other Russ Andrews products I have used (and that’s a lot) the Signature Socket does exactly what it says on the tin. The soundstage is wider and deeper, there is there a reduction in distortion across the board and the finer nuances of the mix are revealed. All this is fine of course but what this product really does (for me anyway) is get me closer to the music. The whole experience becomes more enjoyable and more involving. If that’s what HiFi is all about for you then this product is a ‘must try’. Highly recommended.
