cheapest cable upgrade ever

@pedroeb If you have not heard them, probably best not to assume the worst about them. I have tried a huge amount of Synergistic Research’s portfolio of goods and most made an audible improvement.

Your statement is reminiscent of “bigger is better”, not that that’s what you said by any means. But this is not always the case. If that compound helps promote flow in a more optimized way despite creating a smaller electromagnetic field than a 1.5V battery, that’s all that matters.

Likewise, synergy is everything. All it takes sometimes to remove the magic from my whole system is to switch a few of the tuning bullets in my Synergistic Research cables or move my speakers a 1/4”.

I have the batteries about 2 inches away from my spade connectors that attach to my speaker binding posts...No direct contact... On my rca cables...the battery on those are a bit closer to the connectors...1 inch or less. Best bang for the buck in tweakland that I have ever come across... Strange but true!

I can understand a battery or magnet creating a magnetic field, but I struggling to know what a coated discs does.

Having said that, I have an open mind and I'd love to have a listen, but without an explanation of what it does, I have a closed wallet.
 

I tried this idea on both my USB cable and then my speaker cables. Tried both independently and together.  Unfortunately after extended listening it became apparent that the music was a bit too forced and constrained sounding at the same time. The tweak led to increased listener fatigue. Remove them and after about a minute the sound became more relaxed and engaging. My speaker cables are solid core copper as an FYI.

I tried it in 3 places.

1. No difference. 

2.  Compressed sound

3. Opened up sound with more details without emphasis on upper freqs. This is on the + after the speaker cable going into the xover.

In addition to whatever EM stuff is going on there might be some vibration damping on the wire, too.
