Used to use Quicksilver, but cleaned it all off and now use Deoxit for cleaning and ProGold for treatment. I have sometimes wondered how well the expensive Furutech Nano Liquid works. I have found the Furutech products I have tried to be excellent in most respects, but I have not tried the Nano. I will look into the Stabilant 22 - thanks for the tip.
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.
