Benfits of upgraded connectors

It makes the cable's personality more obvious as it permits a cleaner passing of the signal, providing that has high purity (not Brass) & as few as possible metal parts (not heavy solid bars but hollow tubes) that are direct Gold plated (avoiding the intermediate Nickel plating) or Solid Silver .
Even the quality of the solder matters !
But I think it is not more significant than the cable's conductors at least at Interconnects & Speaker cables as I've had experienced so far.
After all, the manufacturer voiced it's cable with the particular connector that sells it. And certainly it is not adviced to desolder & replace them.
If your cable is available in bulk, you can pre order it with your favorit RCA plugs or you may attempt to proceed by your soldering skills.
On Power cables they say the connectors are of a much more concern & can manage to completely transform the cable's sound ! But I'll have to make my search about this.

Elizabeth just might be right when it comes to the laugh dept. Good connectors keep your gear safe from frayed wire if you go bare when connecting speaker cables.As far as better male or females when it comes to ic's just buy a good basic plug from Cardas if there your supplier of choice. And don't fall for all the hype like different metal's such as rhodium, nickel or copper and brass over platinum and Gold etc etc? I honestly don't think even a bat would be able to hear the difference if there was one..OK I can feel the daggers coming out..

Dear Schipo,
We can certainly hear the difference !
The point is that we have to climb over a certain level of performance first.
And this one demands commitment & tenacity, but most necessarily objectivity & integrity about our wrong choises & the courage to step back & perceive them as wrong.
Of course, money is a barrier but this is not an excuse :
It is one thing to say that you can't hear the difference, and another thing to say that "this upgrade is subtle but costly & I would prefer to change my CDP instead of buying plugs".

ruGeoch: yes you can hear the difference? As long as your doing the changing of the guard. I have been involved maybe a much longer time then you? And I can say when someone else does the change what your perception once was now will change completley. Read Gordon Gow's Speaker Wire Listening Test results. Then say to yourself could I have heard a change over others? And please don't give me the objectivity & integrity bit.Gordon Gow was President of McIntosh Laboratory and I am sure if they heard a difference they would have reported so. They did not, and no one else did either. Unless the gauge was wrong depending on wire length. Also read Images Of the Consumer's Mind by Milton Rokeach. I am amazed on how many are waiting in the wings with daggers drawn when it comes to this topic...lol
