Diy interconnects RCA connectors.

A heads up re: KLEI ’silver’/pure/absolute harmony connectors - they are not silver apparently:
https://www.aurealisaudio.com.au/klei-harmony-rca-issues/

Just silver plated. Bit sad to hear it. But also now feel better having bought the copper harmony connectors.

Any recommendation of Neutrik profi vs KLEI copper harmony? The Neutrik are slightly cheaper but seem comparable quality. The 10K+ (if remember correctly, it’s at least 3-5K for the RCA if not more) mating cycle rating is pretty nice too

I think using silver audio solder is a nice way to get a 'touch' of silver into your setup. I have used Cardas solder so far.

@lastninja - in response to your postng of the Aurealis Audio web content above.

Please checkout the KLE Innovations site and read the Brochure and Technical Paper
https://kleinnovations.com/kle-innovations-klei-products/klei-harmony-plug/

I think you will find that nowhere does it state that the Silver Harmony is fabricated from "solid silver".

It would appear that most people "ASSUMES" solid silver is used simply because of the name assigned to the plug.

Based on that "assumption" is it feasible to conclude that an American Express Gold Card is made of gold? I think not.

The "Silver Harmony" is just a name assigned to an RCA that achieves a higher level of performance that the Copper Harmony, but not as good as the Pure Harmony or Absolute Harmony.

To quote from their documents:

Proprietary mathematical modeling is utilized to produce the Silver Harmony’s ground to signal pin relationship, parameters, and determines the proprietary metallurgical processes that are used.

I think this fact has been overlooked by the people at Aurealis Audio on purpose. They may have stated in their advertising that Solid silver was used and a customer complained and are now covering their "assets"

In fact they seem to have gone one stage further and have actually mis-quoted snippets from KLE Innovations documents on purpose.

For what purpose I do not know, but it would appear they have an axe to grind with KLE Innovations and are willing mis-quote their documents in order to disparage the good name of KLE Innovations in favour of their own.

Personally - I have auditioned every plug from KLE Innovations at length and all I can is that it does not matter the Harmony plugs are not made from Solid Silver - each plug in the range, much like American Express cards, provide a level "service" that improves as you proceed up the product line.

The issues here should not be with KLE Innovations, a company that I trust and respct, but with that post on Aurealis Audio that appears to have no other goal but to disparage.

I finally built some I'cs using the KLEI Copper Harmony plugs. I got mixed results. The sound was a bit more open and clear. That's a good thing. For those who like classical,opera,strictly vocals,or jazz,I could recommend them. But from my experience with all wires and connectors that use silver,the bass becomes impotent. And that's not a good thing for me. The last rca plugs I tried and am happy with the results,are the Neotech dg201's. They seem as open as the Furutech FP126g with
a bit more impactful bass. And they're modestly priced. They also have a bigger opening so you can use more,or larger guage wires. So far,my best design is using 1 upocc Neotech 22 awg solid round wire,1 Neotech 24awg solid round, 2 Jupiter pure silver 28awg solid wires,and 1 Jupiter 26 awg solid wire. I used a 14awg and 18 awg Neotech stranded in pvc,for the ground wire.

I burned them in for over 300 hours and the results were fantastic.
I also got some new speakers,which are a bit more revealing than the Energy RC-70's. I now have the SVS Ultra Towers. I like them. More accurate and deeper 3d soundsatge. The bass is unreal. Fast,very deep,and you don't need a subwoofer. I can't figure out why more people haven't discovered them. And the build quality is great. The Energy RC-70's have a rich midrange. Much better than most all speakers I have heard in their price range. The Vienna Acoustics Mozart might be slightly better,but to my ears it's a tossup. The SVS Ultra Tower comes very close.Not quite as rich,but pretty close. But the inner detail on the SVS is umatched. And the smooth upper highs as well as the Energy's are somewhat dull. But for bass? I've never heard any speakers in this price range that makes such a deep,low,and full bass,without being thumpy.

@dayemo - the copper harmony are better than most other brands, but for the very best results the Silver, Pure and Absolute Harmony plugs really performs.

Since you appear to be into DIY please see the following link

These are my own DIY IC's. They provide very fast dynamics, large image, extended bass with superb bass control and extremely good clarity.

I recommend using 4% WBT silver solder for best results

I stumbled over a tv-coax years ago that has shown to be totally inaudible as an ic when used one lenght for + & -. It is the Vivanco KX-710. Tryed it up against a lot of top-ic`s, nothing comes really Close. A bit tricky to terminate, I prefer to use wbt- type rca`s and solder the minus through(!) the rear screw-hole in the plug.

This coax has also shown to be the ultimate digital coax. Wonder if Vivanco weill ever realise what they have done here.

I have seen a grown divorced* audiophile cry after hearing his system play through these wires.
