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

I built a RCA cable pair with KLE RCA Pure Harmony and Duelund DCA20GA.
They work together very well. It is a very good match for my system.
I like this combination more than Pure Harmony + DCA16GA or Duelund Gold RCA + Duelund DCA20GA.
This thread is quite interesting....

There are the people that like/love the KLEI plugs 

And the people that think they are unworthy - mainly because the silver appears to wear off.

Has anyone considered that the problem may not be with the plug, but with the socket into which the plug is being inserted?

If the socket is even slightly larger than spec, it will exert additional force on the plug which will of course wear off the silver.

I say this because I have been using KLEI plugs for around 5 years and the only model of plug that I have experience the silver wearing off is the Copper Harmony - and even that was after several dozen insertions.

I have used these plugs on several different components, so there is a likelihood that at least one of them would wear off the silver coating, but I have to admit that on all my cables the silver is still intact

I now only use the Absolute Harmony because it is superior sound to all other models in every respect.

For the person that wondered how the Harmony plugs compared to the original Bullet plugs - even the copper harmony was superior to the Silver Bullet - and as I worked up the line the improvements kept coming.

Here's my review of the Copper Harmony vs. Silver Bullet

Hi @williewonka ,
What is a difference in sound between Absolute and Pure Harmony?
Regards,
Alex.
Alex - the Absolute Harmony and the Pure Harmony both perform extremely well.

Perhaps the most telling evaluation was on my turntable which has one piece silver litz harness. The cartridge is a Soundsmith Mod’d Denon 103 with an optimized Countour Line Contact stylus on a ruby cantilever and the phono stage is a Simaudio Moon LP5.3

The following link will give you more details...

I also used the KLEI gZero20 IC’s which had the Absolute Harmony plugs on them for my digital rig and they provide the same outstanding quality.

I now use them on my own "home brew" Helix cables that allow these RCA’s to perform to their highest abilities. 

Hope that helps - Steve

Hi @williewonka ,

Thank you for answer.
Do you think the tonearm cable RCA connector is the most sensitive place in audio system?
I use Furutech 126(G) for my tonearm cable.

I used KLEI Pure Harmony with number of cable in my system.
It always sound very clean, clear and quiet. In some combinations (of cables, speakers and components) it sounds just right, but in some other combinations it can sound too polite in upper mid.
So I need try to use KLEI Pure Harmony instead of Furutech and than I will see how does it matches.

Regards,
Alex.
