Copper Sleeve over IEC

Tonywinsc, Its hard to believe that a 1 " coupler fit over your power cord. You must be using an el cheapo cord.
So, you are out $1.88 for trying,,,
Better to put your money into a quality power cord.

Jim Smith pointed me in the direction of this posting and AA. I picked up a couple of copper couplings at the local hardware store this weekend. I can honestly say this is the cheapest tweak (about $5.00 each) I've ever made to a system that made such an audible difference. I figured, what the heck. $5.00 isn't like dropping another couple or three hundred on interconnects or a grand on speaker wires. The increased bass and level of detail was astonishing. The really great thing is that this isn't some voodoo solution being sold by an audio company. It's something anyone can do at little to no expensed.

Sabledog, no "voodoo" solution. Please tell us what this is doing.

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.

Ozzy, I know Sabledog likes the couplers. It is his crack about voodoo that I am curious about. Does he "understand" why the couplers work in his system and not mine? There is much about this hobby that is just trial and error.
