Graphene Contact Enhancer

Thanks for your review and honest descriptions. I’ve tried to get a discussion going on this stuff a couple times on different forums. Insults or crickets were the common results. 
Yes, breaking and remaking an older connection makes an audible improvement.  Cleaning before remaking the connection improves it further. Not earth shattering, but noticeable.

To say this treatments improvement is strictly due to breaking/making the connection is laughably easy to disprove which I’ve done on two systems.  It goes like this:

Break/clean/make the connections. All of them. Huh, I can hear that. A little tighter bass, a little more detail.  
Do it again, this time applying a VERY thin coat of the treatment to every connection. (Tube pins not recommended)

The difference is not subtle. I’ll resist the temptation to use the overused phrase “an order of magnitude improvement” but damn, it is pretty impressive.  Bass is tighter, the improved detail is really nice, and that detail also improves imaging depth and width. $60 bucks and a couple hours, are you kidding me?

The instructions say the improvement should last until you break the connection.  I live with that, applying it again only when I pull connections. 
To further flip your lid, I treat fuses too.  I did that when doing everything else so I can’t report what it accomplished specifically. 

People with strong opinions without actual experience with the product will, as usual, be ignored.  

Don't have an opinion about audio applications (yet), but in my previous working life my specialty was thermal ionization mass spectrometry.  I used a graphene product (not this brand) but designed for audio applications on all of my instruments electrical connectors.  We were measuring currents down into the 1x10-10 amp range.  It's main benefit was removing vibration induced noise from the connectors mating surfaces...even with mil-spec connectors.  This stuff would even quiet down banana plugs.  I have used it sporadically on my audio connectors, but can't confirm any sonic improvements.

Got home from work and half way expected placebo to have evaporated. Nope, still amazingly better. In fact, seemingly even better than my first impression. Could just disconnecting and reconnecting do this? Maybe, in part. But its intriguing me as to the perceived improvement. The weird thing is that the instruments sound more like an instrument rather than just a non descriptive "sound". Some "sounds" actually turn out to be synthesized vocals. Never noticed that before. Some percussion appears now as a disconnected complementary item. Sorry hard to explain exactly.
