How Good is Walker Extreme SST Contact Enhancer

Rushton, I observed SST to be incrementally better than Pro Gold...let's
say 5% better. To me, a 5% improvement in sonics as a result of contact
enhancer is not equivalent to a 5% improvement in sonics from a better
source, amplifier or speakers simply because the benefits of contact
enhancer are so small to begin with. In my view, the miniscule
improvement using SST does not warrant the additional expense. That
said, some audiophiles find a 5% improvement worthy of thousands of
additional dollars spent to achieve the increase in performance. Also,
the tendency for the SST to flake...and yes, I did apply just a very thin
layer using the supplied applicator...is something I find personally
worrisome, especially where tube sockets are concerned.

Fair comments, Tvad. Thank you. And I apologize because in re-reading the thread I do see that you covered this earlier.

No worries, Rushton.

For what it is worth I used Craig Pro Gold prior to using extreme SST and in my system there was really no comparison. I have not used the standard SST and cannot comment on that comparison. I am sure results will vary depending on the system but in my system the results are well worth the $150 investment.

There's a proudct called QuickSilver that claims to be better than the Walker SST. Anyone know of that claim's veracity? I've not tried either, just asking.
