New Tweak --- Its Fantastic


THE NEW TWEAK

Over the good part of this past year I’ve been beta testing a new tweak, the name of which is "Total Contact." Its a hi-bred graphene contact enhancer that is different from all other contact enhancers that have come and gone for one reason or another. I’m not new to these contact enhancers, having had quite a bit of experience with a product developed by the late Brian Kyle and his "Quick Silver" contact enhancer. The "Total Contact" is different ... a LOT different.

"Total Contact" is graphene based and is not a vibration control. It eliminates micro-arching between two contacts. Micro-arching, much like Micro-vibration smears the sound in our stereo systems. Its the type of distortion that we don’t know is there .... until we eliminate it. There is no break-in as we know it. The sound is improved right off the bat, but what you hear is only a smidgen of what’s to come.

I tested three generations of "TC," each of which was an improvement over the previous incarnation. The final mix was cryogenitically treated and made for a more effective, much smoother application. It comes in a large hypodermic needle type plunger containing 1.5 ml of product and includes a instructional DVD and an application brush.

The application should be applied with a very thin coat to all of your electrical connections .... from your cartridge pins to your power cords. I did my entire system, including the ends of my fuses.

Upon initial application, you will notice an improvement in clarity, correctness of tonal balance and a more overall organic sound. But ... that is just scratching the surface of what this magic paste does. As it cures, the improvements become more apparent. Much more!

There are two real break-through events that happen almost to the day with "Total Contact," one at four weeks and another at eight weeks . At four weeks, you’ll get a real jump in clarity and overall improvement. That’s only a taste though of what’s to come at eight weeks. At eight weeks your system’s focus will make a jump in SQ that is so real - its surreal.

After 40 years in the hobby, and a total tweak nut, I have never heard anything that does what this graphene paste does. The see-through clarity at eight weeks becomes simply amazing. The "paste" eventually cures into a kind of polymer plastic and it seems that the sound improves with each listening session. So, its important that you leave your contacts alone for the duration. If you’re the type of person that continually switches wires in and out, you’ll have to re paste until enough time has elapsed to get "the cure."

The only problem I had was with the first batch and that had to do with shorting out a tube pin in the line stage. Use the "TC" very sparingly on tube pins, if at all. I only had problems with the line stage tube pins. The Amp, CD Player and Phono Stage has had no tube pin problems at all.

Tim Mrock, one of our fellow A’goners, is the developer of the product. Its taken Tim 15 years and several patents to get it right. Tim has "pasted" every electrical contact he can find in his audio system, all of the switches in his circuit breaker box, every contact in his car ... and has used it in commercial applications such as hospital circuit breakers, surgical lights ... and other places where efficiency and long life of electrical components are deemed important.

This product is highly recommended to anyone who truly wants to get the most out of his/her audio systems. There’s enough product in each tube to do at least two audio systems as it just takes a very thin coat on each application to be effective. The last tube was enough to do my system twice and then a friend’s system this past weekend.

PS: There were a couple of other A’goner beta testers of this product as well. Hopefully, they will chime in here with their experiences for comparison. I "pasted" both of Steve Fleschler’s systems a few days ago, perhaps he will comment on his results too. We forgot to paste Steve’s power cords though, so there’s a lot more to be had from Steve’s two fantastic systems.

Almost forgot, that audio myth slide show of Mr Kite that shadorne posted is from 2001. The amazing thing is folks still think like that almost 20 years later. Looking on the bright side, I guess we would not have audio forums if everyone agreed. Kind of the yin and the yang. 😛
All this chitter-chatter, chitter-chatter, chitter-chatter 'bout
Shmatta, shmatta, shmatta, I can't give it away on 7th Avenue
This town's been wearing tatters (shattered, sha ooobie shattered)

That's what makes our town the best
Pride and joy and dirty dreams and still surviving on the street
And look at me, I'm in tatters, yeah
I've been battered, what does it matter

Don't you know the crime rate is going up, up, up, up, up
To live in this town you must be tough, tough, tough, tough, tough!
You got rats on the West Side
Bed bugs uptown
What a mess this town's in tatters, I've been shattered
My brain's been battered, splattered all over Manhattan

I think a lot of the controversy here was generated by obvious hyperbole. I mean claims of reducing electric bills if the TC is applied to the entire house-full of electrical connections is just silly. I’m not an electrical engineer but if anyone can actually explain the logic of that claim I would love to learn!

>>>I actually think contact enhancers, generally speaking, might very well reduce electricity bills. How much they would reduce electricity bills depends on a lot of things, obviously. Like how much energy is consumed per day or month and how many contacts are treated. Why would contact enhancers reduce cost? Because the electricity would be used more efficiently. Kinda like the Shakti On-lines, that were demonstrated to improve gas mileage when used on electrical cables in cars. And kinda like some other audiophile products, WA Quantum Chips come to mind, and perhaps certain line purifiers, act like traffic cops, organizing the flow of the electrical signal and making it flow more efficiently. 👮🏻‍♂️ Obviously an audio signal that is more “efficient” can measured by Signal over (Noise plus Distortion).

And perhaps contact enhancers are analogous to audiophile products that improve the efficiency of how Acoustic Waves propagate through air, e.g. tiny little bowl resonators, SteinMusic Harmonizer, Ultra Tweeters.
Whoa! Hey, relax, fellas. I’m pretty sure someone who doesn’t believe wire makes any difference would not (rpt not) use contact enhancer. Could he be a chain puller?
Uh, WD40 is not conductive so I kind of doubt you’d have much luck with your designer concoction. In fact, it would be self defeating.

Now that the name-calling and veiled insults on this thread have been halted by the moderators, I’ll weigh in on this tweak.

>>>>Not to mention the unveiled insults. 😀

cleeds
First, the notion that the absence of a money-back guarantee on this product should arouse suspicion is just a red herring. Many things are sold without a money back guarantee. If you want to buy a house, a new car or a phono cartridge, you’ll have to conduct your due diligence, and then be willing to assume some element of risk. (Although, in the heyday of the LP era, my audio dealer did offer money-back on phono cartridges. But those days are long gone, I think.)

>>>>Most audiophile products actually DO have a money back guarantee. But I’m not sure this product won’t. Did someone confirm that? In any case, I think it would be a good idea, as Brian with Quicksilver Gold fame, to offer an even smaller amount for half the price.

cleeds
This not a tweak I’m inclined to try. It’s not the cost, which is less than a set of tubes for my tube amplifier. It’s that I prefer connections to be clean and tight and - obviously - this goop would violate that. And if I tried it and didn’t like the result - then what? How do I get the goop off of those connections?

>>>>But think of how good your tubes would sound after treating the tube pins. I’m not hot doggin ya. 🌭 All of the similar silver or silver and gold products, as does this one, improve the connection contact. Apparently, if you need to remove it, it’s easily removed. Chill.

cleeds
Does this goop work? I have no idea but I wouldn’t dismiss it without some first-hand experience. There are some who believe that their knowledge of physics or electronics, or who put faith in what they read in magazines or online forums, allow them to divine the sound of something without listening. I claim no such clairvoyant power.

>>>>>Audiophile Contact Enhancers have been around like forever and have been well received. I’m sure Google is your friend for anyone interested in reviews on-line of Silclear, Quicksilver Gold, whatever. So, we know the basic idea is sound. Chill. ❄️
I read here on this thread that the new product is easy to remove. I’m not talking about other products, although I have had Silclear and Quicksilver and Quicksilver Gold, which your humble scribe found easy to remove, well, not terrible anyway. I may not have tried to remove Quicksilver Gold, you know, back when I had actual electrical connections, I would have left it in place. Looks like nice shiny silver, like silver plate. The trick is not to apply too much or go too far down a tube pin or down the male pin of an RCA plug, you know, since it’s highly conductive.
Nothing so insidious or devious. 😛 Your humble scribe is how I refer to myself occasionally. Your humble scribe and your humble narrarator are used in literature and movies. Alex in A Clockwork Orange, for example, refers to himself as your friend and humble narrarator, if I’m not mistaken.
More on the Furutech product that, and I don’t like casting dispersions, appears to be a copy of Quicksilver Gold, with some familiar sounding innovations, I.e. cryo and “electromagnetic field processing.” I trust the translation is not exact as the Furutech product almost certainly uses pure silver not sterling silver particles. Gee, one wonders if Furutech is following this thread. 🙄

From the US eBay seller,

”Gold and silver nanoparticles will do at the same time stalwart of the unevenness of the contact surface.

A mixture of pure gold and sterling silver of ultra-fine particles of a maximum diameter of 8 nanometers (8 / 1000000mm) by high concentration dispersed in squalane oil.

Furutekku α (Alpha) Process processing subjected to (minus 196 ℃ ultra-low temperature processing and a special electromagnetic field processing), pure gold and further up sufficiently demonstrated by conducting the advantages of sterling silver.”


I’m not trying to hot dog anyone but can contact enhancer be applied to HDMI cables? I just bought my first HDMI cable, the Audioquest Carbon. Controlled for directionality with all the buzzers and whistles. Yeah! 😛
Toothpick it is! The trick will be drinking enough coffee before I do this. ☕️
Question for Beta testers or anyone else, has anyone tried using contact enhancer on non audio connections such as power plug for refrigerator, TV, and light bulbs, including refrigerator bulb, and bulbs in bathrooms, closets, etc.?

Thimk outside the box. 
I know. Nevertheless, that why I posted some things people might have overlooked. Thimk outside the box. I’ve been doing this longer than the average bear. 
For folks asking a lotta questions, good on ya mates!, but you guys should really do some due diligence beforehand. You might not appear to be so out of it. You know, Google is your friend. I know what you’re thinking, sob, but I haven’t run across Graphene applications anywhere. 😳 In certain areas of science, audiophiles lead the way. Lead, follow or get out of the way.

5 seconds after a Google inquiry by your friend and humble scribe, the first hit is,

“Potential graphene applications include lightweight, thin, flexible, yet durable display screens, electric/photonics circuits, solar cells, and various medical, chemical and industrial processes enhanced or enabled by the use of new graphene materials.[1]

In 2008, graphene produced by exfoliation was one of the most expensive materials on Earth, with a sample the area of a cross section of a human hair costing more than $1,000 as of April 2008 (about $100,000,000/cm2).[2] Since then, exfoliation procedures have been scaled up, and now companies sell graphene in large quantities.[3] The price of epitaxial graphene on Silicon carbide is dominated by the substrate price, which was approximately $100/cm2 as of 2009. Hong and his team in South Korea pioneered the synthesis of large-scale graphene films using chemical vapour deposition (CVD) on thin nickel layers, which triggered research on practical applications,[4] with wafer sizes up to 30 inches (760 mm) reported.[5] By 2017, graphene electronics were being manufactured in a commercial fab on a 200 mm line.[6]

In 2013, the European Union made a €1 billion grant to be used for research into potential graphene applications.[7] In 2013 the Graphene Flagship consortium formed, including Chalmers University of Technology and seven other European universities and research centers, along with Nokia.[8]”

GRAPHENE FOR EMI SHIELDING (Duh!)

“Graphene appears to be the most effective material for EMI shielding
(Nanowerk Spotlight) Sensitive electronic devices like cell phones and computers require shielding from electromagnetic interference (EMI). Such shielding – which must be electrically conductive – has traditionally been made of metal, which poses a weight problem in the push to miniaturize and lighten electronics.

Previous research has already demonstrated that ultra-lightweight carbon nanostructure-based nanocomposite materials outperform conventional metal shielding due to their light weight, resistance to corrosion, flexibility, and processing advantages ("Towards cost-efficient EMI shielding materials using carbon nanostructure-based nanocomposites").

In new work, scientists in Korea have now demonstrated that single-layer graphene is an excellent choice of material for high-performance EMI shielding. They found that CVD-synthesized graphene shows more than seven times greater EMI shielding effectiveness (in terms of dB) than gold film of the same thickness.

Reporting their findings in a recent online edition of Nanotechnology ("Electromagnetic interference shielding effectiveness of monolayer graphene"), a team led by Byung Jin Cho, a professor in the Department of Electrical Engineering at the Korea Advanced Institute of Science and Technology (KAIST), suggests the feasibility of manufacturing an ultrathin, transparent, weightless, and flexible EMI shield by a single or a few atomic layers of graphene.”
This just in! Graphene structures. Hurray! Let’s see, what can be look forward to constructed with Graphene, ten times stronger than steel? I’m thinking tweeters and midrange drivers, tonearms, isolation platforms, speaker cabinets, what have you.

“Researchers design one of the strongest, lightest materials known
Porous, 3-D forms of graphene developed at MIT can be 10 times as strong as steel but much lighter.

A team of researchers at MIT has designed one of the strongest lightweight materials known, by compressing and fusing flakes of graphene, a two-dimensional form of carbon. The new material, a sponge-like configuration with a density of just 5 percent, can have a strength 10 times that of steel.

In its two-dimensional form, graphene is thought to be the strongest of all known materials. But researchers until now have had a hard time translating that two-dimensional strength into useful three-dimensional materials.

The new findings show that the crucial aspect of the new 3-D forms has more to do with their unusual geometrical configuration than with the material itself, which suggests that similar strong, lightweight materials could be made from a variety of materials by creating similar geometric features.

The findings are being reported today in the journal Science Advances, in a paper by Markus Buehler, the head of MIT’s Department of Civil and Environmental Engineering (CEE) and the McAfee Professor of Engineering; Zhao Qin, a CEE research scientist; Gang Seob Jung, a graduate student; and Min Jeong Kang MEng ’16, a recent graduate.”
Bet nobody Googled how to make Graphene in your basement. Can’t get much cheaper than that. Also bet none of the naysayers would try to make Graphene even if they could. Even if it was free. They’d rather fight than switch. 🥊 I’ve seen this movie before.
Frank sez, “I had negative experiences with earlier contact enhancers.” Now that’s where you lose me, Frank, since Quicksilver Gold is such a fantastic product. Maybe it was case of operator error, problems with your system, not following instructions, who knows? Maybe you didn’t know how it worked or where to use it. Maybe you never actually used it, who knows? Whatever the tweak, as sure as shootin’, if you look hard enough you can find someone says, I had negative results with it. 😬 Bashing competitors is the favorite sport of tweak manufacturers and their proxies. 😛 Trumping the predecessor, so to speak.

I don’t care why or how TC works. Just like blue SR fuses, duplexes, Stillpoints, Townsend Seismic Sink, equipment stands and Shakti Hallographs, they are essential tweaks besides my various cables and tube incarnations except I found the tweaks stay in my system for a long time.

>>>>I’m not sure I can be quite so cavalier about things. Actually, a large portion of this thread is concerned with precisely how and why this product works, as well it should. I doubt NASA would be so cavalier about how a thing works, especially something that is getting so much attention these days. It is important, for example, to know why Graphene is located on the exterior of the SR Black Fuse, not inside the fuse (as a conductor) as so many have assumed. I doubt the Defense Dept. is cavalier about Graphene. Or MIT. Or China. If we don’t figure out how and why a thing works we wouldn’t be able to know how and where to use it. Most audiophile tweaks really require some sort of explanation as to how and why they work; otherwise we wouldn’t know how to use them in our rooms or systems. You don’t just plop Shakti Stones or Shakti Hallographs just any old place. You have to know how they work. Same for Mpingo discs, Tube Traps, crystals, cables with arrows, even Townsend and Seismic Sink require some knowledge how to set them up properly, no? Have audiophiles really become a group of complacent spoon fed ostriches? 
Frank asked, “Where does one buy Quicksilver Gold these days? Is that what Walker sells?”

Whoa! What? You’re aren’t exactly boosting your street cred with questions like that, Frank. 😬First there was Silclear from Mapleshade. I’m speaking only of silver based stuff here. Not Cramolin, Deoxit, all those Craig conditioners, cleaners, etc. there is Sol Electret from PWB as well that I also use and recommend for electrical contacts. Then there was the Walker Stuff. I’m pretty sure SST is what Walker sells now and has sold for a very long time. Not sure if it was his very first product. Next came Quicksilver from your buddy and mine, Brian. (I carry on with my version of one of Brian’s products, actually, that I got permission to sell from his family. The Tourmaline Gun.) Quicksilver was followed some years later by Quicksilver Gold, in which some Gold was added to the silver. Since I was down with all of the silver based contact enhancers since Day One I think I can say without fear of contradiction Quicksilver Gold was the top dog. 🐕 Having said that, Walker and/or Pierre may or may not have improved their products over years, who the heck knows? 😳 Most likely they have bigger fish to fry🐟 you know, like a $100K turntable.

Dear Geoff Kait, audio insider ...

Where can I buy Quicksilver Gold?

>>>>>>Frank, as far as I can tell it’s not available. Maybe some kind soul has a stash somewhere who can spare some, who knows. Good luck finding some.

Uh, Randy, I hate to be the one to tell you but Tweak (sic) turned out to be the worst contact enhancer ever foisted on gullible audiophiles. The specific problem with Tweek was that it turned into a horrible green black goop 💩after a period of time, plus it didn’t really do anything. So, Tweek is proven all right, proven to turn into a green black goop. Nice try, anyway!

If someone wants to use a non silver type contact enhancer might I suggest Cramolin Red, you know, the one commercial aircraft uses in their communications system? ✈️

Cheers

See p. 1 for Tweak comments - and many other pages

No listening tests + no science + high prices... what does that add up to???

>>>>All I see are positive comments by you and Frank. So, Frank doesn’t like Quicksilver Gold, doesn’t know you can’t get QG anymore but, like you, thinks Tweek is great. I guess that puts me in the color me suspicious camp. 🙄 I had Tweek. That’s how I know it turns into greenish black goop. That’s science, Junior!

What does a 5 second Google search turn up?

“Be very careful using this stuff as tended to gum things up and/or caramelise when dumped in places like tube sockets.”

“Nasty stuff, I can’t tell you the number of RCA jacks that I have seen that once had Tweek on them and the chemical damaged....looking at the jacks under magnification looked like the gold plating had been "blasted" off the substrate....”

“The biggest disaster was the original Tweak (sic), a contact enhancer which was especially good at boosting bass. After many months it turned to goo on your contacts, screwed up the sound and was a real hassle to get off.”



Oops!

Sorry, Frank, it was Tom, not you. On page 1 of this thread. So, it’s Tom whose street cred just went down a notch. 😟 One assumes when Randy suggests comparing Graphene contact enhancer to Tweek blind it’s so you won’t see the black color of the Tweek goop. 💩

Original tweek was great product. This goes way beyond anything I remember of tweek.

It is common knowledge that the RCA is not an especially well designed connector, but it is the standard that designers are stuck with, if they want to be compatible with other equipment.

>>>>While that might be true, there are many other electrical contacts that are not RCA. To whit, fuses, audio power cord plug into wall outlet, EIC connector, refrigerator and other appliance power cords, light bulbs, ribbon cable connectors - I dare anybody!😀 - circuit breakers, headphone connections, tube pins, batteries, TV connection to power cord. Did I miss any?

pop quiz: Has anyone tried painting solder connections in electronics with the Graphene stuff, you know, just for grins? 😛
jetter
The basic assumption that makes this tweak viable is that there is not adequate electricity/signal reaching the equipment due to a loss from micro arching. Stated another way, that the designers of our equipment did not ensure that the full amount of power/signal was being delivered to our gear to ensure proper operation, that our power cords, fuses, rca and xlrs, and speaker cables and their connectors are so complicated and under designed to perform their intended function 100%?

>>>>>>Huh? What? That’s NOT the basic assumption at all! That is actually a perfect example of a Strawman argument - ranting about a false assumption, or a made up assumption. Nobody ever said micro arcing results in a loss of power. Nor does it. What micro arcing does result in is noise and distortion. That’s why all electrical connections in the house - including non audio connections - should be cleaned, at a minimum, to reduce noise and distortion. So, technically, it’s the Signal to Noise plus Distortion ratio that is affected. The power delivered to the gear is adequate even when the SNR Is relatively low. But micro arcing is not the whole story as higher conductivity of the connection is important as well, no? which is why Silver, Gold and Graphene are used in the first place.

There’s no substitute for high SNR. - old audiophile saw
Inside every English major is a pseudo scientist dying to get out. 
The quotidian fluctuations in power delivered at the wall far outweigh and swamp any power fluctuations resulting from micro-arcing in audio system electrical connections. if indeed there any, which I actually think there probably aren’t. Besides audio electronics are designed to account for fluctuations in power. So, cut me some slack, Jack!
It’s a little bit sad when a pseudo scientist completely runs out of ammo. 😢 Can we have a moment of silence? 
I actually don’t feel the same way. I welcome dissenters, whether they’re sincere or not. After all sometimes you can’t tell the trolls from the shills without a scorecard. Or the real skeptics from the pseudo skeptics. And sometimes, there’s a very thin line between science and pseudo science, between physics and metaphysics.

Transient - The leading edge of a percussive sound. Good transient response makes the sound as a whole more live and realistic.

Transparent - Easy to hear into the music, detailed, clear, not muddy. Wide flat frequency response, sharp time response, very low distortion and noise. A hear through quality that is akin to clarity and reveals all aspects of detail.

Treble - The highest part of music and voice. See Highs. (Most often used when referring to the treble control on amplifiers).

Tubby - Having low frequency resonances as if you're singing in a bathtub. See bloated.

Upper Midrange (Upper Mids, High Mids) - The audio frequencies between 2 kHz and 6 kHz.

Veiled - Like a silk veil is over the speakers. Slight noise or distortion or slightly weak high frequencies. Loss of detail due to limited transparency.

Woolly - Loose, ill-defined bass.
Color me skeptical.🙄 Do you guys mean to tell me that you make no changes to the system or add any tweaks to your systems in all that time, 4 weeks, 8 weeks, whatever? I don’t think I ever heard of audiophiles who are that patient, who do nothing at all for that long. Do you just sit on your hands the entire time waiting for a sudden boost in SQ? Many testers already said they keep treating more and more contacts over time, as new applications are discovered, so they must loose track of what was treated originally. 4 weeks starting when? After the first application? After the last application? Weather conditions, time of day, day of week, all those things - and more - influence the sound, too. I suspect this should be filed under, Too Many Variables. If it doesn’t make sense it’s not true. - Judge Judy
Ground control to Tom, what are you going on about? Did someone promote you to Damage Control? 
This ain’t my first rodeo, cowboys. 🤠 I am not (rpt not) disputing there are audible improvements right out of the gate with product. I got on board the whole contact enhancer train 🚂 way back when Ronnie Raygun 🔫 was in office. What I was objecting to, uh, in case anyone missed it, was the claim that differences in sound, if any, after 4 or 8 weeks can be directly attributed ONLY to the product under discussion. You know, to the the many variables issue. It’s the same for ANY product that is assumed to take a very long time to break in, by the way. I’m not (rpt not) disputing the break in, I’m disputing the claim of being able to hear it. That’s all.
Tom, uh, you’re the one being disrespectful. You cowboys don’t agree with something so you start attacking. Same old same old. You never tire.
