Contact -enhancer, fuses - NOS 1260 High fidelity audio cables
| Post removed |
That's the way Total Contact was. $300 for 1.5ml seems excessive, until you realize it is enough to do everything in the whole system and then coat the bus bars, breaker connections, and neutral and ground wire connections in the panel. So basically the whole system and panel. Which takes hours to do, but when done the improvement is what you said, amazing darkness between notes, incredible depth, detail and definition, yet this all comes with no edge or glare, in fact the sound becomes much more smooth and natural. The acid test to see if it really is a good copy of TC, does it work when applied on the outside of wires, caps, drivers, etc? Because TC, and all the related stuff, is much more than contact enhancement. |
I have completed applying the 1260 to most of my connections. I must say that there is definitely a nice improvement. The darkness and quietness between notes is amazing. I can hear deeper into recordings. Backing vocals are clearer and better defined. Listening to "Witchy Woman" by the Eagles has revealed to me some eerily deep background vocals that I have not really noticed nor felt it so strong before. The cost originally did seem high, but compared to other upgrades it is worth it. And I still have a lot of product left! ozzy |
I went ahead and purchased the Furutech Nano at $159 per bottle to get my 'feet wet" with nano enhancer. I find that is does positively impact SQ in both of my systems. audioman58 stated earlier in this thread that he found the 1260 to be even better so I will likely give it a try down the road; but I am pleased with the Furutech at the moment. |
Posted on the other thread. "Pauly, I don’t doubt that contact enhancers like NPS-1260 can and do work, but I do wish they’d tone down the marketing baloney. There is no "nanotechnology" at work here. They developed (or more than likely, "borrowed" what somebody else developed) a medium that suspends graphite, which greatly increases the contact area of electrical connections it is applied to. More than likely NPS-1260 is used in some other area of electronics under another brand name and available for a fraction of the cost." _________________________________________________________ Pauly, rh67, I also have used Stabilant 22 for years. Connections coated with it still shows no corrosion. The best I can answer is the proof is in the sound. Does it improve the sound quality? At this point for me it does. $599 for a bottle is pretty steep but compared to fuses, cables, footers etc. it is pretty remarkable and worth it to me. I just hope it works long term without mucking up and I am not sure how to store the unused portion. ozzy |
First impression: there does seem to be a better more relaxed sound. And yet, there is a better (refined) upper frequency with better articulation. Not hearing anything negative with my first few applications, actually it sounded pretty good. Based on this, I just finished coating all the power, interconnects, speaker cables and a couple of fuses for my amps. So, I’ll see what more time does to the sound. ozzy |

Specifically for use on Audio Gear? Yep and it’s $80.00 on Amazon What is Stabilant 22?Stabilant 22 is an initially non-conductive block polymer which when used in a thin film between metal contacts becomes conductive under the effect of an electrical field. This occurs at an electric field gradient such that the material will remain non-conductive between adjacent contacts in a multiple pin environment. In addition, Stabilant 22 exhibits surfactant action, as well as lubrication ability providing a single component resident solution to virtually all contact problems. When applied to electromechanical contacts, Stabilant 22 can provide the connection reliability of a soldered joint without bonding the contact surfaces. What are its uses in recording studio equipment?Stabilant 22 can be used wherever electrical contacts are used, whether this is in connectors, or in switches. In recording studio applications the number of places where Stabilant 22, 22A, or 22E, can be employed, are almost too numerous to list. When an entire audio mixer is treated (including socketed ICs and card-edge connectors) it is not unusual to find that the distortion and signal-to-noise figures are improved substantially, as well as increasing the reliability of the mixer itself.Many consoles employ "ITT-Schadow" type switches; these can be serviced very quickly using Stabilant 22A, by first flushing them out with isopropyl alcohol and then injecting the switch with Stabilant 22A. Computer-controlled mixers often suffer from erratic operation or crashes. Stabilants 22, 22A, or 22E, can often cure these problems. Microphonics in connectors can be especially troublesome in portable equipment Stabilant 22A, or 22E will stop this. In critical Audio work involving long signal runs, Stabilant 22 on the XLR connector will not only cut noise, but will, in many cases, improve the sound by stopping high-order harmonic distortion caused by thin-film rectification effects. In patch bays, Stabilant is recommended for ring, tip, and sleeve plugs and jacks. Unlike some of the other protective oils which will cross-link (varnish) under the effects of the free sulfur in the brass, Stabilant 22 is chemically stable and therefore, need not be periodically cleaned off and replaced. In recording equipment, the connections to the playback heads can be a source of distortion and noise. Stabilant 22A (or 22E) can be applied to the connectors to eliminate these problems. RF interference can also be a problem in recording, especially with the number of illegal RF power amplifiers being used with CB transmitters. With the passage of time, connectors often build up thin films that act as crude rectifiers. This source of RF interference can often be eliminated by using Stabilant 22. Stabilant 22 can also be used in mastering equipment. Often feedback type cutters suffer because of inexplicable glitches that can be traced to poor connections in the feedback signal leads. Distortion or lead-capacitance-induced phase shift (because of unexpected resistance in a contact) will do much to eliminate the benefits of a feed-back type cutter, and can actually cause ultrasonic oscillation in the system. Stabilant 22 on the contacts is a cure. Why should we use Stabilant over less expensive alternatives?Granted that the material itself is expensive, however it is unique in having a very long useful life once in place. Unlike other so-called contact treatments, Stabilant 22 will not cross-link (becoming varnish-like) under the action of sulfur based curing agents in elastomers, cutting oil residues, or the sulfur-bearing free-machining metal alloys used in some contacts. In most types of service work, the cost of the down-time involved in removing and replacing a board will be much greater than the cost of the Stabilant used to treat the board. Here what is important is that not only will the proper board treatment cure existing contact problems, it will prevent others from occurring, thus eliminating the necessity of repeating the treatment at a later date!In other words, why do a job more than once? In what forms is Stabilant available?The Stabilants are available in several forms. As a concentrate (Stabilant 22), an isopropyl alcohol-diluted form (Stabilant 22A), and an ethyl alcohol diluted form (Stabilant 22E). For example, a given size container of Stabilant 22A will cost about one-fifth the amount of a container of Stabilant 22 as it contains only one-fifth the amount of the concentrate. Another form of packaging is available. Stabilant 22S packages the concentrate such that it occupies one-fifth the volume of an otherwise empty container. This allows the end-user to add his own diluent, and thus saves the added costs of shipping the diluent (e.g.: isopropyl alcohol), as well as allowing the end-user to use an alternate diluent such as one of the Freon-based solvents.In addition a 0.5 ml vial of Stabilant 22A is available for manufacturers to include with plug-in circuit boardsWhat is the difference in use of these materials?Stabilant 22 is most useful where the connections are out in the open - such as card-edge connectors or where the lubricating properties of the material are useful -such as an aid to installing microprocessor IC's or on switches. Where the connections are not too easy to get at or where the user wishes to apply the material to something such as a socketed IC (without removing the IC from its socket), it is easier to use the alcohol diluted form (Stabilant 22A or Stabilant 22E). The alcohol diluent serves ONLY to carry the concentrate into the connector.Is it available in a spray can?No. Why waste the material? We would like to think we are environmentally responsible and safety conscious. This ruled out the use of either a chlorofluorocarbon or highly inflammable mixture of butane and propane as a propellant. In addition even Stabilant 22A for example, has only about 71200th the solvent impact as conventional contact cleaning solvents, over a three year time span. As Stabilant 22 contains no solvent it has absolutely minimal environmental impact and is, therefore, becoming the treatment of choice for many service organizations!Is Stabilant 22 just another contact cleaner?No, Stabilant 22 is a resident potentially electrically active material which through a synergistic combination of effects enhances conductivity within a contact without causing leakage between adjacent contacts. Thus large quantities of the material do not have to be "hosed" on, as is the case with cleaners.How does Stabilant 22 work?Contact failure is rarely caused by a single factor. Thus, treatments that solve only one problem don't necessarily offer a reliable long term solution. For example, cleaners do not prevent the re-entry of contaminants or the reformation of contaminant films; nor do they offer any lubrication. They must be used each time a connector gets dirty. Lubricants in themselves are rarely cleaners. Corrosion inhibitors are neither cleaners nor lubricants and are often specific to one type of metal or plating. Unsaturated oils used as contact treatments can cross-link under the influence of elastomer or thermoset plastic curing agents and accelerants. While resident in the connector, Stabilant 22 performs several concurrent functions. Its very presence in the contact gap will prevent the entry of outside contaminants. It has sufficient surfactant action to lift surface contaminants and hold them in suspension. In cases where corrosion products are present, Stabilant 22 will penetrate them and prevent rectification effects. Due to its high dielectric constant it will act to form a capacitive layer which is in parallel with whatever residual resistance exists in the contact increasing the passage of AC signals. Given sufficient DC bias within the gaps of the contact the thin film of Stabilant will "switch", conducting by quantum tunnelling, and thus limit the resistance of the contact to a serviceable level.What is the 15 ml service kit?This was made up at the request of several manufacturers who wanted a standard kit that they could issue to their service personnel. It consists of a 15 ml dropper bottle of Stabilant 22A and some applicators, all in a small capped cardboard tube that can be tossed into a tool box without damage. As noted, we can provide these kits with special labels when large volume orders are involved.Why would anyone want to buy large quantities of the concentrate?Many manufacturers make large volume purchases, diluting the material for specific applicators used on their production lines. Many end users have found that the material cuts their service costs so much that is more economical to purchase Stabilant 22 in the larger container sizes rather than run any risk of being without the material. The number of uses tends to increase users discover the large number of problems that can be solved by the material. One user routinely applies it to the flashlight switches and batteries it issues to its security guards and has reported that the number of requests for replacement units has dropped appreciably. How can I be sure that Stabilant works?The best way to find out just how well it works is to try it out; that's why we have samples available. Almost every service shop or manufacturer has equipment available where the switches or connectors have become erratic over the years. Use Stabilant 22/22A/22E on them and satisfy yourself. A word of caution. Don't try to evaluate Stabilant 22's performance on brand new connectors. Instead, use it on connectors that are corroded, or dirty or just plain unreliable. We are sure that any organization dealing with electronics will have at least one piece of unreliable equipment on which the Stabilants can be tested!Can I use Stabilant 22 in other equipment?Yes, it can be used in test equipment, cameras, just about everywhere there's a low-voltage signal or control connection. For example, the effect of Stabilant 22 in Computers is to reduce the number of times the system locks-up or crashes, sometimes it even eliminates non-software crashes completely.When used on socketed IC's, photo-couplers/isolators, rotary, push button, or slide switches, or even on BNC connectors, the net effect is usually to make the proper operation of the equipment less erratic, and in the case of IEEE-488A buss- controlled equipment, to cut down on the potential for system lock-ups. Is Stabilant hazardous to use?Stabilants have very low oral toxicity. Under normal workplace conditions no skin sensitization effects have been noted. In the undiluted form, it is non-flammable although if heated above 200° Celsius the decomposition products would burn. And Stabilants are environmentally friendly materials.What is the best way to apply Stabilant to a contact?The 15 ml (and the 50 ml) container have "controlled-dropper" type caps that allows Stabilant 22A to be applied directly to such components as socketed IC's, switches, connectors, etc. Some end users prefer to use industrial syrettes to apply the material. Camel's hair brushes can be used to brush it on card-edge connectors or they could be dipped into the dilute material. Most metering type liquid dispensing systems can be used as well.Does the action of Stabilant deteriorate with age?In some field trial applications lasting over fifteen years Stabilant 22 has shown no sign of reduced effectiveness. With a high molecular weight and a very low vapor pressure, little is lost by evaporation. Unlike some other contact protection oils, Stabilant 22 will not cross-link when exposed to free machining materials such as high sulfur brass, or when used on contacts where agents used to promote cross linking of thermosets or elastomers are present in the environment or in the actual connector components. Unlike non-saturated oils, Stabilant 22does not "varnish".How long has Stabilant 22 been in use?Stabilant 22 has been used in the Audio industry since 1983. It was licensed for sale as TWEEK™ in consumer equipment where the number of satisfied customers runs to the tens of thousands. (TWEEK was a trademark of Sumiko Inc.)Revision |
1/8 the price on Amazon.

When applied to electromechanical contacts, Stabilant 22 can provide the connection reliability of a soldered joint without bonding the contact surfaces. Where can Stabilant 22 be used?Stabilant 22 can be used in all types of connectors, at frequencies from to DC to several gigahertz, on fader's or potentiometer's, or in non-inductive (non-arcing) power-interrupt switches. The number of uses are almost limitless.Is Stabilant 22 just another contact cleaner?No, Stabilant 22 is a resident potentially electrically active material which through a synergistic combination of effects enhances conductivity within a contact without causing leakage between adjacent contacts. Thus large quantities of the material do not have to be "hosed" on, as is the case with cleaners.Is Stabilant 22 cost effective?As Stabilant 22 can be quickly applied to all contacts and connectors in a system, the often difficult diagnostic determination as to which one of many contacts are erratic, can often be eliminated. This can significantly reduce service time in the field and in many cases eliminates the need to return boards for shop service or re-manufacturing. As any service manager knows, the diagnosis of electronic problems, especially where intermittent failures are concerned, is often much more difficult than the actual part replacement; as well as requiring service personnel of exceptional calibre. In many cases the use of Stabilants can thus increase the efficiency of existing staff as well as allowing many connector harness related problems to be handled at a much lower cost.Many of our users have reported savings of from $250 to $3000 as a result of using $3 to $5 of the material. In many electronic applications demodulation (detection) of RF signals in connectors exhibiting thin film rectification effects can either reduce the signal-to-noise ratio or introduce artefacts which can disrupt data flow. Stabilants can cure these problems. While Stabilants have demonstrated that they can cut the cost of both shop and field maintenance; their use in the manufacturing of electronic systems can speed up production as well as reducing rejections.How does Stabilant 22 work?Contact failure is rarely caused by a single factor.

The alcohol diluent serves ONLY to carry the concentrate into the connector.What packaging is available?Many manufacturers make large volume purchases, diluting the material for specific applicators used on their production lines. We can supply the concentrate (Stabilant 22), in 0.5 mL, 15 ml, 5O mL, lOO mL, 25O mL, 5OO mL and 1 litre bottles. The dilute (Stabilant 22A or Stabilant 22E, the latter which is available in a limited number of bottle sizes except on special order), are available in 5O mL, lOO mL, 25O mL and 5OO mL containers. We do not have a 1 litre container of the dilute as 500 mL is the largest size bottle that can be shipped by air (in single or multiple packages) without additional restrictions. We maintain our stock in depth and ship most orders the next day that they are received. ( On large quantities , more time may be required) For companies which want to use the material as a stock store item, we can produce custom labels with your part or stock number. The 15 mL sizes are in dropper bottles, and these are available on request for the 50 mL sizes as well. Custom labelling has been provided for many manufacturers who wish to assign their own stock control number, or to distributors who wish to market the product under their own logo. Obviously this requires purchase in of the product in suitable quantities.Is it available in a spray can?No. Why waste the material? We would like to think we are environmentally responsible and safety conscious. This ruled out the use of either a chlorofluorocarbon or highly inflammable mixture of butane and propane as a propellant.

As Stabilant 22 contains no solvent it has absolutely minimal environmental impact and is, therefore, becoming the treatment of choice for many service organizations!Just how much should be used?Normally, a final film thickness of from 0.5 to 2 mils of the concentrate is all that it necessary. In other words, you want just enough to fill up the interstices between the contact's faces. When using Stabilant 22A, or Stabilant 22E, use enough so that once the isopropyl alcohol (or ethyl alcohol), evaporates the desired 0.5 to 2 mil film of Stabilant 22 remains. In applications to moving surfaces, such as in slip-rings or potentiometers, film thickness should be minimized to the point where "hydroplaning" won't occur.What is the 15 ml service kit?This was made up at the request of several manufacturers who wanted a standard kit that they could issue to their service personnel. It consists of a 15 ml dropper bottle of Stabilant 22A and some applicators, all in a small capped cardboard tube that can be tossed into a tool box without damage.

We are sure that any organization dealing with electronics will have at least one piece of unreliable equipment on which the Stabilants can be tested!What is the effect of Stabilant in audio equipment?Generally it makes an audible reduction in the 'grain" of the sound, where a lot of connections are involved such as in a recording studio, the sound is usually much more open and clean sounding, with a noticeable improvement in signal to noise ratio. The material is especially effective on Schadow and similar switches, as well as on plastic element or wirewound faders. We have been told of many cases where older consoles have been improved to the point where they are back on line, and even some where they sounded better than their replacements!What is the effect of Stabilant in video and CATV equipment?In video applications, the pedestal level is usually improved; often there is a noticeable improvement in detail indicating that the signal's rise time is also shortened. In CATV applications the use of Stabilants can cut customer complaints, speed field service, and reduce RF leakage from connectors.What is the effect of Stabilant when used in computers?The effect of the Stabilants in computers, is to reduce the number of times the system locks-up or crashes, Sometimes it even eliminates non software crashes completely. The material can be used on card-edge connectors, socketed IC's and in the peripheral connectors such as IEE-488A, RS-232C, & Parallel ports. Its use in LANs can often mean major reductions in service costs as well as cutting retransmissions due to parity errors.What is the effect of Stabilant 22 when used in test gear?When used on socketed IC's, photo-couplers/isolators, rotary, push button, or slide switches, or even on BNC connectors, the net effect is usually to make the proper operation of the equipment less erratic, and in the case of IEEE-488A bus-controlled equipment, to cut down on the potential for system lock-ups.Can Stabilant be used on robotic equipment?Yes, not only can it be used on the circuit cards, but often older robotic equipment suffers from erratic contacts in the connections between the electronics section and the actuator part of the equipment even though most of these connectors are of the environmentally sealed type. Shielding case covers are often used to prevent electrical interference from welding equipment and the like. Stabilant 22 is frequently used to ensure that the covers make electrical contact with the case.What about Stabilant in avionics navigation equipment and similar applications?Stabilants have been used in the maintenance of ILS, DME, VORTAC, Loran C, both conventional and digital radar systems in both mobile (seaborne & airborne) or fixed facility operations in addition to use on HF, VHF, and UHF communications equipment.Has Stabilant been used in mobile communications or paging?Yes, not only is it being used by a number of police forces in servicing their communications equipment, it is being used by the industry as well.Is Stabilant hazardous to use?Stabilants have very low oral toxicity. Under normal workplace conditions no skin sensitization effects have been noted. In the undiluted form, it is non-flammable although if heated above 200° Celsius the decomposition products would burn. And Stabilants are environmentally friendly materials.Can Stabilant be used by untrained personnel?Thousands of applications of the consumer version of Stabilant 22 have been made over a period of several years now without any reported problems.What is the best way to apply Stabilant to a contact?The 15 ml (and the 50 ml) container have "controlled-dropper" type caps that allows Stabilant 22A to be applied directly to such components as socketed IC's, switches, connectors, etc. Some end users prefer to use industrial syrettes to apply the material.

HFC Innovations, the name, and the product page read like late night informercials. Does it slice and dice and make Julienne fries too? This page is my favorite https://www.highfidelitycables.com/technology/ High marks for using high school science experiment stuff to get audiophiles to part with their money. I especially love this, "Magnetic conduction is a new patented form of conduction, implementing specially arranged magnetic fields to concentrate the signal within the conductor." ..... don't anyone tell them about skin effect which they don't seem to have solved. Oh boy! More power to them. Pet Rock's for audiophiles. Who'd a thunk it! |
Update: Ok guys this stuff works. The first day I thought it was a scam after initial application I was hugely disappointed. Today on my second listen everything opened up with a massive soundstage, improved dynamics, and 3D like presentation. Not sure why there is burn period but this is one of the better tweaks on the market. -Alex |
Like others here have experienced, when first applied (it does not dry-it never “dries”, apply it then plug it) there is a period where the sound “goes dark” and the higher frequencies become slightly muted. Some dynamics seemed to be softened. IN MY SYSTEM the volume was slightly affected as a result but it didn’t last very long. By the end of day one dynamics were close to baseline. After day two the treble issues lessened substantially. What seemed to be occurring through this break-in was a different quality to the spatial character within the soundstage. I was noticing a more coherent portrayal of instrumentation; a “fullness” of the overall sonic presentation. When the higher frequencies came together, a reduction in “harshness” was evident. Less strident? Less “glare”? Just sweeter, easy to listen to. What I also am noticing that with low volume listening, I am still hearing these 3D enhancements to the soundstage which weren’t apparent prior to using NPS-1260. Overall in my system this stuff works great. If any other users here have experienced the same or different using NPS-1260 please let us know... David |
Hi ozzy I just did the speaker end of my speaker cables first. Just a thin coat on both sides not even covering the whole spade. Want to be able to get it off the speaker spade if i did not like it. With in 4 hours of listing time i was applying more to the power cables. I was told the thicker the coat the longer the break in time. I will and have gone back to add more to the power cords prongs, i liked what it did their too. Go slow you can always add more. Each time you add some over the old it will take time to break in. Do not put it on sloppy, spider web between prongs on power cords. My 1260 is on to stay. |
Got mine today and only pasted the Power cords. Yes, I definitely heard a difference and resolution, soundstage which appeal to me even at lower volumes. I imagine it will get better as more hours are placed on it. Next job is to clean and paste to all RCA connectors and speaker cables. One caveat is that I was a fan also of PPT products but unfortunately I ran out so this is the next best alternative. |
