Contact Enhancer Deterioration


I had been impressed with the initial application of both Walker Audio and Quicksilver contact enhancer products. There is an immediate increase in clarity, extension, and dynamics. The effect was not subtle.

However, I am now convined that over the ensuing weeks to months, the enhancer becomes detrimental. It happens gradually, so it is not obvious. The sound becomes soft, diffuse, veiled. Removing the enhancer with some alcohol has brought things back into focus.

One last experiment was whether this detriment was just due to loose connections or tight connections. For example, it has been postulated that these enhancing material form a bonded and continuous surface. Power cable connections, while they seem to be quite stable, are always moing due to vibration and expansion of metals. This will create cracks in any polymerized material. However, items such as fuses and speaker cable spades tend to be more stable due to the connector pressure and location. Would these surfaces also benefit from removing the enhancer? The answer is yes.

For those of you who are using contact enhancers, I urge you to remove this and listen to your system again. Feel free to report your findings. If anyone has any other experiences, that would be good to hear. If someone feels that there is a particular place that benefits from a contact enhancer long-term, I'd be interested. It seems that the conservative thing to do is to clean your contacts, particularly if they are prone to oxidation.

I found an unopened box of the produce I mentioned, it was called Cramolin, I forget its active ingredient, if I ever knew it. Seemed to work but I stopped using it as I am a dealer and found that for every customer who liked the idea of having it on a product another who would think I had ruined it. I change my connections so often I have never worried about them oxidizing, perhaps I should. I got stuck with a bunch of Tweek when the above review came out, I never used it so can't comment on its qualities. I had customers asking for it on the basis of the glowing reviews it had received. I am holding on to mine until the revisionists decide it was a miracle product after all. Don't laugh, I have seen this happen before.
Stabilant 22 is the best. IMO far better than Caig products, which in my experience have left discoloured residue and muckiness that had to be cleaned up over time.

Be warned though, Stabilant 22 comes in various ways. The best is the pure concentrate, which is a small 15ml bottle that costs near $90. The other types are diluted with ethanol and various alcohols.

I would avoid the diluted types and only use the pure concentrate.
