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

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.
  • Here is a recent review.  Easily the best mod or tweak I have ever encountered in my 35 years of audio.  

OP: great thread. My digital IC and I believe most (if not all) of my Teo Audio IC's are terminated with these plugs.
Hi @grannyring ,

Contacts of RCA connectors, tube sockets, power plugs, tonearm headshell bayonets,...
are a big issue in audio.
Does Total Contact Enhancer solve all this issues?
