Are contact treatments worth the money?

If audio (or electrical) connections did indeed provide optimal transmission: contact enhancers could not further affect one's music reproduction, but to degrade it, or have no effect on it at all. I think that would be more accurate.

It's o.k. though, I can bang my head against the wall all day. The only result is that you would still spend your $30+ on something that is touted to have a real effect on an electronic system that has negligible effects on the basis of the laws of nature, which is what your system was founded on in the first place.

I am glad to see that the audio salesman who chimed in with a plug for his shop did offer a money back guarantee. That was refreshing. His caveat that your system may not be good enough to resolve the difference with and without the tweek was a bit pathetic (although only in 1 out of 10 times does this happen, so my dear friend and future customer, don't be offended, your system is good enough to be sure).

Sorry for the cynicism, tweeks are accessories. Accessories carry the highest profit margin in the store where you shop. Caveat emptor.

Yes, yes, but the connections are mechanical & flimsy. (Silver) "Conductive grease", which is non-fancy name for the stuff, is used for moving mechanical contacts... it helps with electrical & thermal conductivity.
OTOH, there is a risk of metal migration (silver into the gold plating of the contacts).
See fo example products like this.
I use such a product, cleaning it every 3-4 months (with acetone -- take care not to touch ANY plastic with acetone) & reapplying.
No doubt Walker's products has its unique merits except one: the price. The industrial equivalent, while not cheap, is far more reasonably priced.

Bicycle_man, no retailer or manufacturer has chimed into this thread. Only various of us who use the products in question.

I am very sorry, Rushton. I mistook your post as a plug and did not read it carefully enough. Please accept my apologies.

I agree to disagree. This is another audiophile topic that can go on endlessly in debate. I have stated my thoughts about it, and those who disagree with me have stated theirs. There it is.

I reiterate that I am glad that some companies offer money back guarantees on their tweeks. That, to me is important. That promotes experimentation, which is a critical aspect of improving one's system.
Cheers!

No harm, Bicycle_man. We can certainly agree to disagree for there is much room in this hobby to differ. I agree that experimentation is important as we seek to improve the enjoyment we get from our respective systems. Sharing actual experiences is one of the great values of the Audiogon forums.

Best wishes,
