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.

So if you are interested in the complete review please go to http://www.image99.net/blog/

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

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.

Snopro - I found that the answer to your question is dependent on the track

For example: I have some tracks that appear to have less bass, but it was actually due to the deeper image - the bass had moved further back and was therefore lower in volume. Some might interpret that as less bass.

I didn't find the Silver Harmony sounded any thinner - just all around better
- better image and more focussed witn more "space"
- faster dynamics
- finer details

The bass was significantly deeper on tracks with really deep bass - like R&B and pipe organ music

Both Harmony RCA's were warmer than the Eichman Silver Bullets I originally had

The Silver Harmony are well worth the extra $30

Having said that their performance is very dependent on the wire you are attaching them to.

I use solid silver interconnects, which are extremely detailed and I find very neutral. Both the Copper and Silver Harmony RCA's brought out the best in the interconnects

Hope this helps

I plan on having some cables made up using Mogami 2549 and the Copper Harmony RCA plugs with the ground floated on one end of the cable run. Since Mogami 2549 is all copper, would it be wasted money to get the Silver Harmony plugs instead?

And has anyone found cable manufacturers doing builds similar to the build I want? Thanks...

I DIYed my own set of cables using a the exact same design as yours, Sbrownnw. But I used a set of VALAB Rhodium Plated Carbon Fiber RCAs though instead of the KLE. I finished them off with a nice sheath of Nylon Multifilament. I don't know if they are world beaters because I really can't tell a difference among cables.
