Add small pigtail wire off negative out of amp.WOW


A great tweak that is completely free (if you have bits of spare wire laying around)
Add a small pigtail of wire to the negative five way binding post of the amp. just hanging off the post, not connected at the other end to anything.
Works. Some implementations work better than others, but the result is greater clarity, and better lower frquencies.
How this works is ???
Anyway, for those who do not want to take a risk of doing something off the wall themselves, a low priced version is avalable from EVS for $30 a pair.

A few other companies make a similar product.
(I have no affiliation with EVS, and mention them ONLY because the product is not overpriced, and is basically a small tweak, at a fair price for it.)
My own attempt has led me to making clusters of Ferrites with wires sprouting out of the clusters. then a wire to the negative terminal of the amp. and a similar single ferrite with the wire sprouting at the negative terminal of the speakers.
I find more stuff off the end of the wire 'helps' for my particular setup.
Anyway. If you can find a way to do this tweak, and if you have a pretty good setup, you may find it is a great tweak. And dirt cheap too.
My cost for my complex adaptation is for the Ferrites $6.30 only, since I had the wire on hand as scrap. I used some bananas to stick the wires on the amp five way, but i had those laying around too.

After reading this thread I made a 5 inch piece of solid core 12awg speaker wire with a banana on the end for termination. After A-B testing over a dozen times I almost thought I heard a differance. I pluged the two pigtails into my amps neg speaker output for the test.
I didn't conclusively hear a differance.
I'm all for these cheap tweeks and have tried a few that I could hear a differance.
It may be amp dependent or system dependent.
I gave it a shot.
I really wanted it to work.
