Tbg, I think Sabledog is refering to the fact that he can tell the improvement, its not one of those things that you have to convince yourself that there may be an improvement.
What I have noticed is a tightening of the bass and a clearer defined soundstage.
That being said, some posters have stated no improvement and one said it made the treble glare.
The point Sabledog and myself are making is that for a very minimal cost you can experience if the copper sleeve is an improvement for your equipment.
