anyone upgrade their RCA connectors on Cardas RCA cables?

Prior to Sept 2012, in 2005 or 2006, Robert Woodland who was ETI by name, sold his portion of the business to ETI. ETI went into voluntary administration in Sept 2012 and the existing directors of ETI re-purchased ETI in Oct/Nov 2012.

Up to Sept 2012 Keith Louis & Patricia Eichmann were earning royalties on their concepts and ideas (IP and Products) sold by and through ETI. From Oct/Nov 2012 onward, Keith Louis & Patricia Eichmann have received no further royalties from their IP and Products even though ETI has been and still uses and sells their IP and Products.

You should know that Keith Louis Eichmann invented many more products than just the Bullet plug for ETI, in fact, most of them.

Even though ETI were instructed to stop using and selling KLE's IP and products, by Keith Louis & Patricia Eichmann, ETI have continued to use and sell KLE's IP and products.

As a result Keith Louis & Patricia Eichmann decided to begin again and started up Keith Louis Eichmann Innovations (KLEI), in 2013/14, by releasing their next generation Eichmann Bullet plugs, the new and improved KLEI Harmony (Bullet) plugs."

Thanks, @mofimadness,

This history has always been a bit murky.  Not to challenge you, but do you have further references?  

I certainly don't have a horse in this race.

@decooney -thanks!

btw, 10 mOhms cable-connector bond resistance is a lot.. typ. I see ~10uOhms..100uOhms in my lab!

"Cardas will state they have cables that measure the same and sound different"

- haven’t seen two cables, even the same model, measuring exactly the same in 40 years! LOL 

design/manufacturing reality is harsh, there is no ways to find two (even same model/brand) amps/pre-amps/speakers/etc sounding the same.. tube amp changes sound every hour.. listeners age as well! LOL 

"@westcoastaudiophile ...tube amp changes sound every hour.. listeners age as well! LOL"

Ya know it's a really good point on both fronts. I have been listening to my tube amps at 2hrs vs 6hrs over the past 4+ years, and question myself sometimes if its the changes in the tube amps for different reasons, or my hearing changing more as I get older in the same day listening session.  Strangely enough, listening on a late Sunday night after a nice long weekend, can sound amazing for whatever reasons, less static in the air -or- less static in the brain after some nice relaxation and rest. I just hope I can maintain hearing long enough to still enjoy it.  Cheers :) 

I would highly advise against it. I wanted to change the terminations on my Cardas Quad 5C speaker cables. The wire used by Cardas, is coated with a varnish/shellac coating, that is a btch to get off, in order facilitate soldering. I tried melting it off it with my soldering iron, which only made a gummy mess. I finally bought a solder pot. It worked, but made a mess of the cables ends. Better to keep the original connectors, and use Caig pro Gold, or another good contact cleaner. I don't think much would be gained using a different connector anyway.
