Cardas RCA Silver connectors

Just adding an alternative opinion.  I have used both Furutech XLR and power cord terminations.  They are excellent in all regards.  I have not used their banana plugs, but I have used the Futurech locking RCA connectors.  The outer shell screws down to compress the shield material to grip the RCA connector onto the equipment.  Two problems here.  The shell needs to be unscrewed to release the grip and this means the shell extends forward and doesn't allow you to insert the center pin that far into the RCA input.   The second problem is that I never felt that it provided enough grip.  It was always a compromise on how far I could insert the plug versus how well I could tighten the locking mechanism.  In the end, I felt the normal stiff-spring type RCA plugs (like a normal Monster cable) worked better in gripping the connection and allowing me to fully insert the RCA plug.  In my experience, Furutech produces excellent top-end connectors (based on the metallurgy and sound quality), however I have got to agree with Erik that their mechanical designs leave much to be desired.  I would avoid using any sort of locking connector design and just stick with the normal conventional design.  Then it just becomes a decision with brand and metal/plating choice.

Ah, some additional info.  I have used the older Eichmann plugs in the past.  If the KLEI use the same plastic material, I would be careful when soldering on the ground/shield pin.  The plastic material tend to melt easily and can skew the ground pin.  I would attach this plug to an RCA input to act as a holder/heatshield while soldering.  Also, sorry if I'm repeating info you already know, but when connecting/disconnecting this type of RCA plug, always push on / pull off directly.  Never twist this plug when connecting or disconnecting from equipment as it can bend the single ground pin when you do this.
