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.

The Canare RCAP-C series RCA connectors are supposedly designed for 75ohm spec.

According to BJC, "These Canare plugs are designed for the best possible impedance match with 75 ohm video coax"

Williewonka, thanks for posting the response from KLEI. While I understand their thought process and belief that their design is an excellent choice for digital applications, their plug still has one specific characteristic impedance and cannot therefore 'match' other different impedance designs. It may however still sound fine in such applications.

Bill - I think that is a very fair assessment!

Dragon - I also found 50 and 75 ohm RCA's from Pasternack

Cheers guys :-)

Ooops - in the posts above the impedance numbers should have read ...
50, 75 and 110 ohms - my mistake - hate these virtual keyboards.

Apologies
