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.

If you would like more information from KLE Innovations then use the following

o Email - KLEinnovations@clubtelco.com

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.

Other questions are ...

How many hours burn-in have the cables had? I know the Copper Harmony plugs require more than a 100 hrs burn-in...

Have you contacted Douglas Connection and what do they Douglas Connection suggest?

Perhaps the Mogami 2549 wire is not that good?

From my experience the KLEI Copper Harmony plugs have a very good and focused mid-range, once run in :)

I have given the new cable set over 200 hours. For some sources with certain media, the cable set sounds great. For other sources with other media, the cable set sounds unacceptable. Overall, I just don't think this cable set is a good match for my system and my media. I have read similar experiences with the fist generation bullet RCAs...

Yes, I did talk to DouglasConnection. He has a great deal of Mogami 2549 experience and always does a continuity check for phase and as a quality check (center pin to center pin and ground to ground). The Mogami wire has very high quality control, as it is used in pro studios plus DIY and other high-end audio equipment manufacturers, so I highly doubt the 2549 is bad. I did switch the cable leads and they all sound like I described in the first paragraph. Doug does not any experience with the KLEI RCAs nor did I and my cable build was the first set. He has wired up many, many different cable configs with exceptional results.

I'm going to sell these at very good prices and go with some Mogami 2549 with either Neutrik Pro-Fi or Furutech 126(g) RCAs. Please PM if anyone is interested in these cables. I'm sure they sound great on other systems, just not mine all the time. I have 2 four foot pairs and 4 three foot pairs with the shielding floated at one end with a directional mark and black cable mesh for each pair for a very professional looking setup.

I think this a great cable set. It just doesn't work in my system.

Sbrownnw - I know you like mogami - and so do many others, but there could be architectural issues that may be causing your problems and the Copper Harmony are just bringing them to light.

Maybe trying the Copper Harmony with a cable specifically designed for interconnect use would be a much better option.

All of the cables I have tried were designed specifically for interconnect use and worked extremely well with the entire Harmony RCA range.

The signal from instruments like electric guitar and Microphones have a much larger dynamic range than the signal in a home audio interconnect and as a consequence - the cables designed to handle these dynamics may have different attributes like Capacitance, inductance and impedance, form those cables specifically designed for home audio use.

So perhaps a cable designed for the higher dynamic range may not be the most ideal cable for home audio inerconnect use.

Based on my excellent findings with several vastly different interconnects designed specifically for home audio use - I think the issue here is probably the Mogami cable - the Copper Harmony is just highlighting the issues that other RCA's seem to be muting.

I hope that makes sense

I disagree.
