Wireworld Platinum Eclipse 7 XLR Balanced Interconnects Review Highlights

Wireworld's newest iteration of its product line are the Model 7's, compared to the previous Model 6's. They have incorporated a DNA-like spiral to the conductors, which for the Platinum Eclipse XLR's that I tested, are solid silver.

Because my past reviews of Wireworld showed almost unmeasurably low reactive impedance, I ran a little experiment by requesting review samples that were 20 feet long.

Finally, a measurable impedance, but it was less than 0.5 ohms. The 20 foot standard "Pro" cable (cables that are used for stage performances and connections from microphones to recording consoles) that I also tested for comparison, delivered an impedance of 5 ohms, 10 times more than with the Wireworld.

The difference was audible, but it is difficult to put into words. The Wireworld had more "life" to the sound. Theoretically, with a higher output impedance of the preamplifer and a higher input impedance of the power amplifier, there shouldn't be any difference. But there it was.

Here is a short video about the Platinum 7 XLR's.

Here is a comparison between the Wireworld Eclipse 6 and Eclipse 7 speaker cables.

Introduction to the Wireworld Platinum Eclipse 7 XLR Balanced Interconnect Review

When I started pubishing Secrets, it was because I had an enlightening experience with cables. That was 20 years ago. I had attended CES, and a startup company gave me a roll of flat speaker cable. I wanted it only because I needed somethign to put under the rug in my home theater to go to the rear speakers. But, when I turned on the system and watched a movie, I noticed the rear speakers had more high frequencies than with the replaced cables, which were 13 gauge stranded zip cord.

I realized that cables could make a difference. Secrets was launched. However, further reviews of cables did not yield audible differences in most cases. I was disappointed. Then I began bench testing cables, and found major differences in the reactive impedance. I became more enthusiastic about the high end cables that began to populate the marketplace at an accelerated pace. Yet, still I was having difficulty hearing the differences that I knew in my heart must be there.

A few years ago, I met David Salz, the President of Wireworld. He showed his cables to me and explained the physics behind the designs. They made good sense, so I requested some for review.

What I found was the lowest reactive impedance of any cable I had ever tested. Some of them had such low impedance, the test equipment could not measure it. Now, I knew I had some cables that I should be able to hear differences. However, it was still difficult. I wrote it off to my age (I am almost 70 now, and my hearing has been affected by those seven decades).

I decided that I might be able to hear the differences if I used a long cable. So, I requested a 20 foot pair of their top model, the Platinum Eclipse 7's in the balanced configuration. I used them with a Pass Labs Xs preamplifier and a pair of Pass Labs Xs-300 power amplifiers.
