Benfits of upgraded connectors

Well, I admit I don't know exactly why they sound different. But I do know that I can easily hear the removal of a 4 ohm resister from my crossovers, and removing connectors is an even greater change in clarity and depth although they measure much less than 4 ohms.

You guys must have fussy electrons.

...and very revealing speakers also !

On the other side of the coin, there are those that will swear that nothing beats bare wire connections. LOL

You mean the patent of 47Labs for RCA plugs I suppose.
It is interesting but very restricted by design, for it is only permits a plain symmetrical solid core configuration.
But for speaker cable, if the conductors (and the braid) are silver, it is true.
Now even if it is true for the power cords, it is also very inconvenient to the point of masochism.
