SILCLEAR, like all tweaks, has its own sound and effect. I personally use it, as it is what I bought from Pierre at Mapleshade (he is such a good salesman, isn't he?). Haven't tried the Walker SST or the Quick Silver. They may be much better; I wouldn't know. Friends with good ears say the Quick Silver stuff kicks major butt, a real value. Again, wouldn't know.
But I DO know the best way to apply the gooey crap! Clean your connections with whatever you use (I use Flitz; VERY cool stuff) and then get out a lint-free disposable wipe (available from any optometrist or related business). Apply the SILCLEAR onto the cleaned surface with a paint brush (fine tip), using a VERY TINY AMOUNT! People slather this garbage on! MAJOR mistake! The film left must be about an angstrom thick. (Okay, okay, maybe not an angstrom, but you get my drift.) Then put another tiny amount on the lint-free cloth and start rubbing the area with the SILCLEAR dabbed cloth directly on the equipment surface or plug/termination and just tightly squeeze as you rub the SILCLEAR INTO the surface. The cloth will absorb the excess in a very short while. Rub until the SILCLEAR is basically invisible except on very, very close inspection of the desired surface. Be careful not to get the SILCLEAR on anything else, as it is highly conductive and can cause a bridge, an arcing --in short, a disaster! Seriously!
This stuff works. But will it IMPROVE your sound? That is not a question anyone can answer but YOU! Try it! Most manufacturers have a 30 day guarantee. Nothing to lose.
Fact is, I don't think I could use up all the SILCLEAR that Pierre sells for $30 or so, in 100 years! If you do it right, you need amounts that are truly miniscule. BTW: I REALLY liked the effect it had on fuses. Absolutely KILLER! And really a cheap, cheap tweak that works, when amortized over the life of the SILCLEAR supplied.
But if you're using SILCLEAR and you're using it up fast, you're applying WAY too much. Remember: "Less is more".
Hope this helped. Happy listening.
