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

o Website – www.KLEinnovations.com (nearly ready)

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.

Sbrownnw - my observations with the Harmony line is that they simply enhance the performance of the cables they are attached to without adding "colour".

Adding them to my silver IC's actually improved their warmth and fullness.

Food for thought - the metals used in these RCA's are actually proprietary alloys that perform "as good as" pure silver and pure copper.

So, how much better is each model than the next ...
- If I were to rate the Silver Harmony as 50% better than the Copper Harmony
- then I would rate the Pure Harmony as 40% better than the Silver Harmony
- and the Absolute Harmony only being 25% better than the Pure Harmony.

Yes - diminishing returns!

For me (and my budget), the Pure Harmony is the best "value" or "bang for the buck" because the level of improvement they brought to the performance on my silver IC's was extremely good. They are noticeably better than both Copper and Silver Harmony.

I have Absolute Harmony on my analogue rig, which I believe will augment the resolution capability of a cartridge upgrade I am planning.

The Pure Harmony are on my digital rig because I think they compliment the resolution capability of the DAC - if I upgrade the DAC then I will consider upgrading those to the Absolute Harmony also.

In short - I try to match the resolution of the RCA to my cables and to the components they will be used on and within my system

You may find the Silver Harmony to be the best "value" on an all-copper cable, but the Pure Harmony may also provide enough of an improvement to warrent that additional expense.

It's your budget, your choice!

Hope that helps :-)

I would suggest the Absolute Harmony... http://www.image99.net/blog/files/a8494e8645dea3d750d109f819103099-61.html

Sbrownnw - since you are into DIY I was wondering if you are up for an
"adventure"?

I'm currently running an interconnect with a very different architecture. It's
similar "in principle" to the Anticables Interconnect, with a slight
twist.

For construction details see

I've used silver for the signal conductor, but you could simply use a single
strand of CAT6 in it's place.

For a 3ft IC you would need 9ft of CAT6, and 3ft of teflon tube - so it's pretty
cheap - a little more if you want to put a nylon sleeve on it.

They do require the KLEI rca's to perform their best.

I know the silver/copper version with the Absolute Harmony is exceptional
(close to the gZero6) and I think the "all copper" version would
provide some stunning details with that warmth of copper that everybody
loves.

The Copper Harmony would be a good match

Anyhow, if you are up for an adventure give them a whirl - you won't regret
it - I can pretty much guarantee it :-)

As a bonus - this design with the copper Harmony RCA's also perform
exceptionally well as a digital S/PDIF IC.

It's not for everybody, but those into DIY might find it worth while :-)

Thanks Williewonka.

I did not DIY my cables. I had Doug at http://douglasconnection.com/ make them for a reasonable price (cheaper than other Mogami RCAs listed on this site for sale but don't quote me since I am not affiliated). If people are interested I would contact Doug directly.

I am really enjoying my KLE Copper Harmony RCAs with Mogami 2549 wire. :)
