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.

I have just completed a review of their Silver®Harmony RCA Plug - the next level up in their line. See my blog for the full review

http://www.image99.net/blog/

It has...
- significantly better imaging
- slightly better dynamics
- much deeper low end
- extended top-end details
- and very transparent

I also tried the Copper®Harmony RCA Plug on a Van den Hul "The Name" 70 ohm Interconnect bridgeing from my Pionner Elite DV-45A DVD players s/pdif output to my Schiit Bifrost and it performed very well - better than the original Van den Hul RCA's that came on the cable.

Personally - for the $30 extra I would go for the Silver®Harmony RCA Plug.

Hi Williewonka,
Can you tell me if the harmony silver plugs midrange is full sounding with nice tonal density or thinner sounding then harmony copper plugs?

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
