Eichman RCA's - what makes them so good?

I've just installed a set of these on a silver interconnect I have and the difference in details was very noticeable. The image has become very focussed with more depth and the micro details have also improved consideraby.

I realize the silver is probably responsible for the improved resolution, so is the design responsible for the improved imaging? Will the copper give me the same image improvements?

Has anyone out there tried both the silver and the copper (or gold plated copper)
- if so what difference did you notice?

Alternately - if you have only used copper
- what were you using previously?
- what differences did you notice?

I am using these on my analogue stage, which I thought was pretty good - until yesterday.

I'm thinking of trying the gold plated copper on the digital side - or should I just opt for the silver - the curious side of me wants the copper, just to see what the differences are, but the pragmatic side is saying that if I'm not happy - I'll need to replace them with the silver :-)

If it's the design of the rca that's more responsible for the improvements' then going for the copper would be more cost effective

Any feedback appreciated - thanks

AES Standard rates copper as Standard for Signal transfer ability (=100%), Silver for example is 106, gold is around 90 and everything else is much worse.
When the unit has very cheap RCA input plugs (brass with gold plating for example), they are in the area of 60, that means, they reduce any input signal by min. 40 % from what is possible.
You sure about that % reduction? What does 106 mean, then?

I don't think much of the Eichmans; A cheap plastic plug,
Eichmann plugs feel cheap but they claim their research concluded that high mass is an enemy of good sound in a connector. So they seem to be cheap plastic for a reason.
