KLE RCA plugs are the real deal!!


I ordered a set of KLE RCA Pure Harmony plugs to use for a pair of interconnects using Duelund 16ga wire. I previously built a set, with good results, using standard switchcraft plugs. The difference, even without break in, was staggering. Although the Switchcraft plugs sounded good themselves alone, however, when doing a direct comparison to the KLE's, the difference is clear. The cables using the SC plugs sounded harsher (especially on high end) when compared to the KLE. The cables seem to have a "free-er"(FLOABT) sound or more flow. Seemed as if the SC's were holding something back. 

As far as building the cables, the separated solder posts make things way easier. Everything is quite compact (especially for larger wires) in the SC plugs. The removable grommets are a nice feature if one wants to use thicker cable wraps, shrink tubing or shielding. 

One other area I think the KLE's are great for is trying wire combinations without soldering. With the "V" shaped solder posts, one could "wrap" the ends somewhat snug and use the wire locking screws. You would still have to be very delicate when hooking up...however this is something that is pretty much impossible with the SC's. 

As I plan to build my entire system's cables, KLE will be the plugs I use on everything. I highly recommend

Agreed on the Total Contact paste.  Amazing stuff! Glad to see you are onto this wonderful tweak. 
These are easy to solder and hold up just fine. Just need the right technique. The thin coating will mark superficially easily but is a complete non issue. These are excellent low mass bullet plugs that make great shielded and unshielded RCA cables. They sound wonderful and just get out of the way with no editorializing.  Seems no product will please all, but it helps to know how to work with these. 


I use the KLEI with 16 gauge twisted pair and a 1/4 inch copper braided shield.  Plenty of room.  

Lots of cable builders, including myself, use these and have never had an issue with the quality of the conductor used on the plugs. I make many cables weekly with KLEI bananas and RCAs and am thrilled with the ease of use and sound quality.  
Goodness that opening is big enough to fit a 12 gauge twisted pair. I have done it .... with a shield! Most ICs are made with16gauge and thinner. That is my point. I even made a double run 16ga set using the Schroeder Method. Fits easily. Confused with this one for sure. However, I suppose if one starts adding Thicker synthetic coverings space could be an issue. I have found these types of coverings hurt the sound however.

I never use the screws as they are not enough strain relief IMHO. I always use a nice double wall adhesive lined heat shrink.

I made an RCA set that both I and the customer felt sounded terrific. 
Treat all those connections.  I have.  Speaker crossover etc.,, Fantastic stuff.  Should try it before you knock it.  I would be willing to split the cost of a vile with one or two of you.

The total contact paste is really not a paste as the consistency helps it spread very easily and a little bit goes a long, long way. The kit comes with a nice painters style mini brush that is used to paint all connectors Etc...

I simply paint the surface of the solder connections and component lead outs on point to point wired crossovers and tube amps. I also paint the tops of capacitors and transformers.

One just needs to be very careful not to produce an unintended conductive bridge. Just use a very little amount on the brush as it spreads very thin, and as I said l, goes a long way. Do not apply so it’s thick and gloppy, but rather thin and spread evenly.

It also works wonders on power cord spades, speaker connectors, RCA male pins, tube pins etc...

While inside my speaker crossover I also pasted/painted the internal speaker wire connections where they solder to the drivers.

Many won’t go as far as I did as they are not comfortable working inside of gear and I understand that. However, a good place to start is certainly on all the various connectors in our system.
I have found very, very little difference going from the Copper to Silver to Pure. I feel there are two real choices. Copper Harmony if cost is an issue and Absolute Harmony if you want the best. The other two add unneeded complexity to the line. My honest opinion.

These take 100-125 hours to burn in fully based on my evaluations.
