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.

@Yping, I've seen the Mogami 2549 from PerformanceAudio.com for $.77 / foot.

@Yping / Williewonka, after my KLEI RCA cables broke in I experienced a very wide and tall sound stage. One I have experienced before. It almost seems like some sources are out of phase it is so wide and tall. Have you experienced this?

Thanks!

Sorry, the 3rd to last sentence should read:

One that I have never experienced before on my system.

Yes - I connected one pair of my DIY's out of phase - pretty strange results,but it was immediately noticeable.

You can tell just by removing the cover and looking at the connection.

The RCA's do present a much larger image though - very 3D

Hope that helps

Yes, the Copper Harmony RCA's present a much larger 3D image, very nice :) Are you not liking what you are hearing?

I really like what I'm hearing from my better sources (vinyl and CD). On my OK source (tuner) and my below average source (comcast cable box using their built-in DAC to stereo analog out) the KLEI Copper Harmony connectors seem to make a questionable source worse. I currently have the KLEI Copper Harmony connectors and Mogami 2549 throughout my system. I am going to try some older cables (Mogami 2549 without the KLEI Copper Harmony) between my comcast box and my Audio Refinement preamp and maybe between my tuner and my AR preamp.
