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.

I'm about to advertise all my gear!!! Was going to switch to crafting or maybe flower arranging.....
i use an ennacom connecting b0oh terminals of the speaker connectors.

i have heard the evs in my friend's system. i heard a minor improvement.

i generally seek more robustness and texture, rather than clarity and/or speed.
I wonder why manufacturer's just don't include this inexpensive tweak with their new amps on delivery ? Placebo effect ? Hmmm....
Hmmm.... I just spent $10,000 on this amplifier, and the manufacture recommends for proper performance dangle this scrap piece of wire from output.... Oh, that would be well received. HA
