  Found them. Audio Prism EVS IMHO a must have tweak. Go for it. Not a dealer for them.

Is this them?



They were call EVS Ground enhancers.

Review here:

https://www.hifizine.com/2011/06/evs-ground-enhancers-a-collective-exploration-of-a-tweak/

We had a tread about them here:

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

And another one on AC:

https://www.audiocircle.com/index.php?topic=87809.0

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.

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).
