“I know it when I see it” runs the quote and I’ll throw this picture out for your delectation. These have now been sent out to a couple of local WBF members and I’ll leave them chime in with their thoughts on sound quality.

Thanks Mark. Yes I ordered a pair to see whether they were useful or not - I didnt have particularly high expectations after all they are only sockets lol (or so I thought).

I decided to undertake the requisite change on my NVO Spa II phono stage output. After installation I played familiar music and immediately noticed a much quieter noise floor. Actually so much so, that I turned up the volume more and couldn’t hear anything so thought it wasn’t on until music burst into the room. Strange since I didn’t see anything wrong with the existing plugs.

The sound was fuller in the mid bass with rich tone and lots of space. Bottom end hefty per Bocch mains plugs.

All in all a great little upgrade. I shall implement elsewhere.

excellent news Bill, I’m hoping mine give me an equal uptick however I need to enlarge the holes in the wooden chassis before I can proceed.

I did need to replace the copper ground cross wire - there is 1 ground wire that bridges both sockets. I used a higher guage. The grub screws make it easy to terminate.

€450 per 0.75m.
I needed a pair.
There was a discount running when I purchased.

*sorry to go OT, Mark.

Bill are the grounds directly connected to chassis? If so, and no noise was added, that could be as responsible for improvements as anything, or solely the improvement. With several designs I have to keep isolation but cutting a small slot between the RCA's, as the improvement is very audible; but running direct connection does the same thing. .

Hi,

No the grounds aren’t connected to chassis. I left the grounding scheme identical to before just enlarged the gauge of wire used. It is the bare wire in the picture - it isn’t touching any chassis either.

But it looks like it makes contact from the nut, as the wire goes into a metal piece that looks to be touching the nut? Is there an insulator somewhere I can't see?

That is very good point. It is as I can’t see an insulator between that and the chassis nut as you correctly pointed out. I can see the insulation on the old sockets adjacent.

Hopefully Barry will install his tomorrow so we know whether the socket itself has benefit.

There's nothing wrong with that so long as you don't get any audible noise from it. In fact it's a big advantage as you don't have to cut the line between them as I talked about. (although it looks like your other sockets could use the line) That is at least, for ultimate performance.

I was taking another look just now. That white ring you can see on the back is separated from the black and red rings so can easily be replaced to the other side hence insulating it from the chassis. That said, being that I have much lower noise now, I’ll stick with what I did (by accident).
