Graphene Contact Enhancer

So true. I have experienced the initial impression of improvement only to be more indifferent after a short while. I see no guidance on how often it should be reapplied. But early on I was very careless applying it to my tube pins and watched several "red plate" due to my messiness. So it is conductive that much I know. Now after applying, I wipe it off with a Q-tip which removes excess but leaves a smear of the nano film which safely creates the improved sound quality. Tweaks under $100 are worth trying I'd say. 

Metal does get exposed to air and causes oxidation. Cleaning it off will make a better contact. I use deposit and a q tip to get into small contacts. Its amazing how much dirt black stuff is on the q tip. It does work.if you want measurements take the ohm meter or scope and prove it. I think most people wash thier hands and can see the water is changed color or smells better. Maybe we should measure that with a scope. Sometimes the art of science works with common sense.people can do what they want it's called freedom and I'm glad we have it to listen to music.enjoy the music.

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.
