Is this them?



They were call EVS Ground enhancers.

We had a tread about them here:

https://www.audionervosa.com/index.php?topic=2646.msg29055#msg29055

And another one on AC:

If I am not mistaken, marketing if these was eventually taken over by AudioPrism, the folks better know for making the Quiet Line devices.



But good luck finding any of them them as I believe the company closed up shop.

I was just looking at the AN thread and it contains a link to some DIY instructions for building your own version of the ground enhancers.

I had them. They worked very well.

Hah, I even started the thread

Maybe somewhat off topic but:
Would something like the ground pigtail work on the ground connection located on the Fyne 501SP?

I still use mine. Try on the amp end, then try on the speaker end. Also try on the + lead separately from the - lead. Results vary in each position. Since my preamp inverts (tubed) I wound up with them at the speaker end on the + lead (best to my ears).

Me too. Probably at least 12 - 15 years ago. As you said, they worked very well
