rca plugs - comparisons?

Mrtennis, Pjwd,
you are indeed quite right, I think. Crimping or a good screw-down connection is - theoretically at least - to be preferred. If however soldering is done right and you manage to get a good and tight metal to metal connection first before applying a touch of solder - we at least - could not really hear any difference.
By the way, while doing these experiments, we found out to our dismay, that the original soldering on those quite expensive cables we used was terrible, to say the least. More often than not, metal to metal conduct was not made, but the joints just bathed in solder. This experience motivated the members of our group to check and resolder all our wires if necessary. The results, I assure you, were
staggering. ( transparency, micro-dynamics, resolution in general)
Cheers and happy listening,
Detlof

I have compared Eichmann Silver, Cardas Silver, WBT Nextgen Silver, and Xhadow silver on a custom made cable. Result:

Not much of difference! Why, because you must consider the jacks of the gear. Many components use cheap Chinese gold/brass jacks. It is the total interface connection that matters. I did try Nextgen plugs and Nextgen jacks and there is a difference in sonic quality.

Very good point, Sonic_Genius! Our gear in those tests mentioned didn't however. Our jacks were premium ones. Should have mentioned that.

Sonic_genius, could it be that all those you tested really are roughly equivalent, and the Nextgen jacks would have improved them all about equally?

a connector that i like a lot is the neutrik pro-fi spring loaded rca connector.
