Cable review Custom Silver Vs Polk Cobra 6 Shorted Parallel Vs Kenkraft-Labs Zeus in a SS system

 Here is an interesting review/shoot-out of three speaker cables in a High End system.

First: The review by J A Garcia of Porta Mallorca, Spain

1) Custom 1.5 m. pure silver made with 4 cores 37 strands 0.08 mm and 2 cores 14 strands 0.14 mm. with pure silver Z banana plugs. It's a 12 parallel configuration: Very clear and detailed sound with stunning sound stage and great presence voices and instruments. I don't know resistance, inductance and capacitance values since my friend have not the machine to measure it.  Very nice sound really with the most balanced and natural sound of the 3 speaker cables for my taste.

2) KenKraft-Labs Zeus 1.5 m. pure copper and silver with copper banana plugs. (please google Kenkraft-Labs for more information). Very clear and detailed sound with great sound stage and presence voices and instruments, but for my taste the sound is not so soft and detailed overcoat in the middle high as my Custom silver speaker cables. Very good sound really but not so natural like my Custom silver and Cobra.

3) Polk (King) Cobra 1.5 m. pure copper six parallel shorted semi-round version with WBT pure silver banana plugs.: Very clear and detailed sound with excellent sound stage and presence voices and instruments. Stunning midrange similar to my Custom silver. Very natural sound really but high is a little below. I suppose it's because of the pure silver cables.

So, comparing the 3 speaker cables (listen session next to 40 hours) all they offer a very good sound and here you my preference in order:

1st Custom Silver
2nd Polk Cobra Six Parallel shorted semi round version (custom made by your truly).
3rd Kenkraft Labs Zeus
 
The System
 
Speakers: Viking Acoustics TubeMaster (98.5 dB sensitivity 8 Ohms impedance)

Amplifiers: Symphonic Line RG2 MK5 Preamp and RG7 MK5 Power amp.
 
Closing remarks
  • I recommended the six shorted parallel configuration as this is an Solid State amplifier. Shorted parallel reduces Capacitance and Inductance values.
  • A written comparison between the vintage Polk and a modern high-end cable is rare.
  • Senor Garcia writes well.  This is published with his kind permission. Thank you, Senor.

Polk Cobra Speaker Cable User Guide (Updated August 2021)

Introduction: These cables are rather special because of the design and manufacturing method that is unlikely to be replicated. ·          So called ‘Litz” speaker cables are easy to find. But unlike some so-called ‘Litz’ cables, Cobra is a true ‘Litz cable’ (not just Litz woven cable). The positive and negative strands are braided together without any Teflon (or similar) insulators. The individual strands are electrically isolated only by enamel (magnet wire or Litz wire). ·          The enameling process is world-class. There is no oxidation almost 40 years after manufacture! ·          A single run of Cobra contains 144 woven strands, 72 strands each for positive and negative! ·          The strands are made of extremely thin high purity copper. This seems contrary to what a speaker cable should be (more suitable for interconnects if one really thinks about it). They look thick due to the enamel. ·          One of the weaknesses (in my humble opinion) of the Cobra desi

Polk Cobra, the amplifier killer? Part 1 (updated Mar 2022)

Image
 Oh my, these Cobras can kill! I just typed 'Polk Cobra Speaker cables' in my google search (31/1/2021) and the got the following results in order of ranking. Arthur Salvatore's high-endaudio blog followed by two (eBay/hifishark) ads and the fourth result was "I hooked up the dreade d Polk Cobra Cables" (my emphasis). Forum comments on Polk Cobra cables are replete with phrases like "amplifier killer", "only suitable for Tube amplifier", "fries your SS amplifier", "be warned", "high capacitance" etc. I will try to debunk this myth that the high capacitance of these cables caused all those failures. I write this post with a foreboding that I am going to get flamed by some 'Polk Cobra experts' and past users. Well, bring it on, my Hifi-Brothers. Cobras did not kill my SS amplifiers, even six of them together! When I got my first 25ft pair of Monitor Audio Super Speaker cables (Polk Cobra, UK version), I was
