Too bad you cannot try it, since you have such a strong opinion of the stuff.
I have been around the block a few times with many so-called tweaks, enhancements etc. And I have never been shy about calling out a product that does not work and or not worth the money.
But, the 1260 really is a remarkable product!
It is nothing like cleaning connections or adding some contact cleaner. This product must do something more, perhaps it seals/shields it from RF/EMI perhaps it does have some magnetic properties, but I really don’t know.
But I TRIED IT! And it really improves the sound quality!
Closed minds will not advance the discussion. It just makes the users and the naysayers go round and round to no end. Try it before you comment.
