KLEI Copper®Harmony Phono/RCA plugs (vs Copper Bullet) by John Withem (JW Audio)

Yes, I have tested the KLEI Copper®Harmony Phono/RCA Plug against the Copper Bullet Phono/RCA Plug.

I made an IC with the new KLEI Copper®Harmony Phono/RCA Plugs and one with the older Copper Bullet Phono/RCA Plug, and the KLEI Copper®Harmony Phono/RCA Plug was a great improvement. I also took it to an audiophile friend of mine and tested in his system with the same results.

• There is more energy and more extension in the highs.
• The symbol work on Keith Jarrett “At The Blue Note” was the best I’ve heard to date. The symbols sound as though they were in the room… Amazing 🙂
• Attack is better throughout the whole bandwidth.
• Bass was forceful but very clean and high energy.
• Focus was excellent, imaging was also top notch.
• Soundstage was open and airy, a bit larger than the Copper Bullets.
• Mids were very neutral compared to the Copper Bullets.

Hope I have answered your question fully and I know you test you products very well, but I have a vast amount of audiophile friends and systems from $5000 to $80,000. I would be honoured to beta test anything new you have to offer. Just a thought…
