Copper®Harmony RCA Plug - a new breed

I was contacted by KLE Innovations recently to review their entry level RCA connector (plug).

I have no idea why - Maybe due to a blog that I maintain?

Anyhow - I was a little skeptical that the Copper Harmony RCA Plug could significantly better my existing Silver Bullet RCA's, since they share (i.e. visually) very similar design principals.

So I set about planning a testing strategy based on about 30 tracks that, over the years, I have used for auditioning various audio components, who's purchase I was considering.

Well, I didn't even have to wait for the Copper Harmony RCA Plug to burn-in to realize they are something extremely special.

Anyhow - to cut to the chase - the Copper Harmony RCA Plug delivers an exceptional performance which improved upon details, dynamics, imaging, etc... of the Silver Bullet RCA's that I own.

Now, I have not compared the Copper Harmony RCA Plug directly to RCA's that conform to a more "conventional" RCA design, mainly because my Silver Bullet RCA's had already demonstrated their superiority.

So - the Copper®Harmony RCA Plug resolves to a very high level of performance and it is very very quick - perfect for just about any duty in the realm of audio - including their use on digital cables!

Because of their ability to allow the flow of extremely small "micro details" in an audio signal, I believe they would also be ideally suited for use on those turntables that employ a one piece wiring harness - especially when using moving coil cart's.

Please note - I have no affiliation with KLE Innovations and was not paid to participate in the review.

I am just very impressed with what I consider to be a stellar product and feel it would be beneficial to share my experience with the members.

@Williewonka, thanks for the recommendation, but I do not have any digital cables in my audio system (tried to keep everything analog). Only two components with DACs are the Bluray / CD player and my Motorola / Comcast cable box and they are internal and use stereo analog on both. I do have HDMI cables but they carry video only and I use a passive switchbox separate from my audio 2 channel gear.

I hope to upgrade the Rega RCA plugs on my RP6 to the KLE Copper Harmony next.

Oh, the older set of my Mogami cables with the Pro-Fi RCAs sold over the weekend.

Sbrownnw - Yping is suggesting a better RCA, but that really depends on the tone-arm/harness combination...

If you are using the standard Rega Arm without any mods - then go for the Silver Harmony or Pure Harmony

if the internal wiring has been upgraded then go for the Pure harmony or even the Absolute Harmony

For something like the Audiomods Arm - Absolute Harmony - nothing less

But one thing for sure - the improvements will amaze you :-)

The Mogami / KLE Copper Harmony cable combo seems to be really breaking in and almost sounds too good if that is possible? Incredible soundstage width and depth, with great mid and bass punch with overall amazing clarity, especially with my vinyl source. My system has never sounded better.

With this said, I wonder if the KLE Silver Harmony is the correct path for my Rega RP6 RCAs? Could they be too responsive or upset the copper mojo of my current setup?

Sbrownnw - my observations with the Harmony line is that they simply enhance the performance of the cables they are attached to without adding "colour".

Adding them to my silver IC's actually improved their warmth and fullness.

Food for thought - the metals used in these RCA's are actually proprietary alloys that perform "as good as" pure silver and pure copper.

So, how much better is each model than the next ...
- If I were to rate the Silver Harmony as 50% better than the Copper Harmony
- then I would rate the Pure Harmony as 40% better than the Silver Harmony
- and the Absolute Harmony only being 25% better than the Pure Harmony.

Yes - diminishing returns!

For me (and my budget), the Pure Harmony is the best "value" or "bang for the buck" because the level of improvement they brought to the performance on my silver IC's was extremely good. They are noticeably better than both Copper and Silver Harmony.

I have Absolute Harmony on my analogue rig, which I believe will augment the resolution capability of a cartridge upgrade I am planning.

The Pure Harmony are on my digital rig because I think they compliment the resolution capability of the DAC - if I upgrade the DAC then I will consider upgrading those to the Absolute Harmony also.

In short - I try to match the resolution of the RCA to my cables and to the components they will be used on and within my system

You may find the Silver Harmony to be the best "value" on an all-copper cable, but the Pure Harmony may also provide enough of an improvement to warrent that additional expense.

It's your budget, your choice!

Hope that helps :-)
